6 California Butter. From the Faclne Rural Ftom.) The complimentary notices which oro re ceived from the East, concerning Iho good keep ing qualities of California batter, do not fully satisfy ns. Thoy imply that we have merely made a lucky hit in tho mode which wo have adopted for preparing our butter for niarkot; and it seems to bo expected that we should acoopt them ns a liberal concession on the part of thoso who could not conscientiously admit tho product itself, nside from its stylo of going to market, among tho flrst-clnss dairy produots of tho land. Wo uro not, howovur, disposed to complain of any slight, or ovon want of appro elation, on tho part of our dlstnut customors; for wu are nwaro that it would bo casting n worse, slight upon them to stipposo that they did not know thnt butter could not bo kept good, thnt was not good when it was taken out of tho churn. It is not to complain of tho want of our full complement of praiHo, but rather to inspiro con tldcnce on tho part of tho producers of Califor nia butter, that wo hnvo takon tho Hubjoct in hand. This is olio of the very few products in regard to which our pooplu are willing to admit that other portions ot thu country possess suporlor advantages; but if thoy had concoded certain other claims to their Kustvru neighbors, and withheld this, thoy would buvo nnived nt h fairer and uioro judicious distribution of agricultural honors. Thoy havo evidently been led into this mistake by tho prating of Science. Tills lady has condescended to mako froiuotit visits to the dairy, of lato. Possibly those visits have been a littlo too frciiiicnt; for though soma of her hints havo been of practical bene fit, many of her conclusions havo been un sound, und hnvo misled her too confiding vtita rios. It has been remarked thnt whan a ludy takes out her gold watch in u crowded street car to inform horsclf of Iho timn of day, her fellow tiiiHScliiturs are justified in thu conclusion that she has not carried a watch a very long period of time; and by tho same rulu wo limy suppose that those who display among tho masses an elaborately and highly burnished case of science, from which dangles a long chain of Hounding epithets, huo not long been In possession of liio same. Science has condescendingly called on lier poor relation, Agriculture, nud hat seouied to tuko a particular fancy to tho dairy department. Hlie has furnished dairymen with an anal) bis of grasses and soils, arid told them in what localities tho component purls of butter nro to be found in their greatest purity nud abund ance; and in this connection wo havo been assured that California is not among the few favond spots where first-class butter can bu made. Wo nru willing to admit that wo hnvo not yet seen an) thing of the California mako that is quito up to thu unco famous "Oruugo county butter, of Now York, or that ripials tho now celebrated l'hiladelphla butter; and among tho many dairying districts of tho Ilust then) are probably other favored hpols w hi re, during a (iiiif season of each year, a giudu of butter may bo made which we cannot upml. Hut wo are nut disposed to nccipt any classification which places California butler In tho "ordin ary," or even in tho " good grades ;" fur wu assert that, with thu exception of thu strictly " fancy" article, our butler is superior to that of iaistern manufacture, From our observations of tho olfects of cli mate on milk, wu cannot see how that of Cali fornia cau lie iithorwlsu than favorable to butter making. Where tho condition of tho atmo sphere Is such that thu milk sours before thu cream rises, and when) tho cream becomes tahitul and moulds a fow hours after skim ming, wo cannot expect as much butter i. 'inn the sumo amount of milk, or as good an iiltlclons In situations which allow the cream amplu time to rise, and do not render it Un able hi tho slightest t.iiul during thu butter making processes, It will, perhaps, lie remem bered by tho readers of tho Piiknh that Harris Louis, of Herkimer county, N. V., recently gave, through Iho columns of our paper, his opinion of tho probable ellccts of our remark ably pure atmosphere mi chccHc-iiiitMiig; stat ing that among other advantages which wu might expect to derive fioiu our climate in this product, cheese uiadu and cured under such circumstances would possess long-kei ping qualities, Mr. Lewis, in bis letter lo the I'iuhs, limited bis observations to chccso-muklug; but , wo uro confident that ho and every other ex perienced dairyman will agree with us that these climatic ndtulitiigcs are equally available ill butter-making. The uniform temperature of thu climate of Calilornia undoubtedly giies uniformity to California hultiT, and it is this quality, which is imparled to it men by tho food of which the cow partakes, which gies it much of the re markable keeping quality for which ours Mem of packing is especially credited, "t'linoy but ter is pleasant to read about, and it is really delicious eating; especially where the con sumer brings to the feast a bit of his own fancy; but uniformity in butter is a quality far more desirable than fancy; especially where it Is uniformly good, or even belter than good, as is the standard butter of Calll'oriiii. It people do not go into ecstasies over California butter, on the. other hand their senses are never shocked by it as they are by a largo portion -perhaps three quarters -ot that which is made In the ljist. It is interesting to observe the almost liuiid manner with which the retail purchaser of i astern butter makes his acquaint ance with tho article. His sense of smell has rcctivi'd so muiiy gioss allrcuits of this charac ter Ihut ho does not bring It in close proximity to his nose, but "scents it from afar at first. When the nose, as a partner in the purchase, assents to the Wirgalu the taste is consulted, and after Mime dilibeiutlou, accomp inlcd by an ominous scowl und a suspicious smacking of the lips, tho purchase, is perhaps completed. Similar scenes nro enacted ocr Iho butter plate at tho Utile. It is scarcely considered u breach of hospitality or of table etiquette for the guest to lift the butler to his noso before spread ing it ou his broad. Hut wo sen littlo o( this iu California. As it is safe to eat a California apple In the dark, so can wo spread, as well at tat, our bread in pi ace, with no noisome stench or fiaor to molest or uisko us afraid. What we have said in regard to the keeping qualities of California butler being more atlrib. uUble to our climate than to our mode of pack ing, should not bo considered as evidence of a want of faith on our part iu this mode; for we tbluk that our butter-makers achieved a fortu nate hit when they adopted It. Wo want no butter -firkins in the State, though butter packed ill them here would undoubtedly keep (letter than ill those places where they arc iu general use; but our loug, two-pound roll . seues uutiy advantages. In convenience and neatness in marketing it caunot be surpassed; and a slice from one of them furuUhes a bo coming occupant fur the butler plate. Enrolled iu thin cloth, and pickled iu large buttercaaks, it cau bo safely transported to any distance. We hope that by improving our dairy stock, aud by iucrtased iacililira for making ami mar keting bultrr, we shall Is) able to compete aa successfully with Eastern dalr)Uieu Iu regard to price, as we now do iu the quality of th product; and that we shall soon export largely of this article. The exclusive exportation of grain fortunately units the emergencies of a newoountry; but all farmers aro nwaro that if continued it will exhaust the vitality of the soil, and they do not noed tho croakings of ns flavors to stimulate them to an endeavor to substitute something of a different character as soon ns practicable. For this purpose nothing la bo well adapted as dairying. It enriches in stead of impoverishing the soil, and whatever enrlchos the soil, enriones the owner of tho soil. Wheat, Fruit, Potato-bugs, etc., at the East. From th Pacific Rural Press. In Pennsylvania, Now York and somo othor Eastern States, whent growing is ovidontly being rosuscitated, and tho goneral report from this crop is at present exceedingly favorable. Fruit is also looking woll; but the potato-bug is looking docidodly bad. In somo portion) of Pennsylvania this dostructivo and odious post is greatly annoying the farmors. It is asserted that thoy travel by rail not on the rail fonco, as old-fashioned bugs hnvo been in tho habit of doing, but by tho railroads of tho country. Tho theory is quito plausible, for it is well known that tho potato-bug, ns allying machine, is n falluro; and no visible means of transit has yet been mado known by which ho reaches his destination, llo has been caught " steal ing n ride" ou tho nxtos and other pnrts of railroad cars, nnd though oveu a larger propor tion of his, than of tho human .race, is crushed aud dumped into otoruity by tho improved facilities fortransportatlon, thoro wilt onough be ieft for purposes of propagation. Among other current agricultural intelli gence received from tho East, Mr. J. 11. Jones, of Itocbostor, N. Y., writes us as follows, under date of July (ith: " Aftor a loug, cold spring, wo aro having a fine growing summer. Wheat, th it lookod so brown and lifeless in April, has thickened up, aud is fully an average in all tho Eastern Statos. Corn looks well nnd nil other spring crops. (Irass is hoavy.

Well, wu must fight them." A Short Cut to Peach Culture. It is to cut off liny old branch of a peach treo, stick It into thu ground it may bo used for n beau-polo while sticking there and it will (alio root, boar splendid poaches scorning the assistnnco of irrigation performing nil tho functions of an old-stylo pe.ich tree, nud requir ing liono of tho cares nud labors which have hitherto been bestowed upon that class of trees. This, it seems, Is tho way thoy manage, these things about Stockton. The occupation of thu nurserymen in tho vicinity of that celebrated citv is evidently uoiuu. coins, nnd will soon bu gone. Thu grand patriarch of this now order of fruit trees, which now stands ou thu ranch of Mr. Learned, near that place, was originally n common garden slake. It Is now pointed out to thu effeminate, youthful occupants of our gardens nnd nurseries us nil example of what a treo oau do that is forced to rely ou its own re sources; u noble self-made peach treo. If sur veyors could bu induced to make their stakes of the wood of Iho peach treo and use them iu their exploring expeditious, what a start It would givo to thu horticultural advantages of the country I and if thu early settlers would use this wood for their fence posts, how tourists and excursive journalists would praise tho country! For if this system was practised, tho passing tourists nud "our reporters" would only havo to climb to tho top of a four-board fence and till thoso dear littlo hats, then eat, drink and bu merry. It is true thnt iu doing this they might Incur Iho risk of presslngoiit somo of the studied dents aud kinksthatnii ed itorial and tourlslicul hats aro expected to pos sess, and thereby render their weunrs liable to b mistaken for ordinary mortals; but alter nil, what is fame! PiioTKirriNii Vaunisii. A simple invention for the prestation of cards, photographs, and, in fact, of aujthing likely to bo injured by moisture or dirt, has just been announced. It consists of a preparation of gutta-percha iu solution. This liquid is thrown iu u very flue spray over the article to bo protected, by uu atomizer, lly this process u thin film is pro duced, and when tho liquid part has evaporated, as Is very speedily done, tho object is coated with a translucent substance, impervious to water, (lutta-percha, iu its pure statu, is of n semi transparent grayish color. Hut its trans parency, as a covering for pictures, depends on Iho thinness of the film. The gum first needs to la purified, nud thou, if it lias not been treated witli alehohol, it is soluble in chloro form or ether. The process of dissolving it is in ilsolt a purifying one. The ether, Mug highly volatile, verv soon disappear when the spray is deposited on any object. A drawing or photograph thus protected cau bo washed, tho gum not being permeable by water, nud resist ing any amount of heat so long as it is wet. It Ix'giiK to soften, however, at a temperature of ISO- Fahrenheit. Hut this is a temperature to which our climate naturally subjects no thing. This simple invention might como iutu very practical ami general use; and if it did no more than to give additional security to the work of the camera, it would be a highly val uable invention.

It is produced by the action of nltrlo acid, mixed with oil of vitriol, upon glycerine, tho sweet substance obtained when oils nud fat are steamed. It is one of tho most treacher ous explosive substances known to chemists, aud frightful accidents have been caused by iu cautiously using it In its crude state. In tho course of many endeavors to counteract or re duce the sources of danger attending the use of nitro-glycerine, M.

I Hints on Hop Growing No. 7. Drying Hops. Our apology for allowing the present num- I her of this series of articles to follow so closely upon the heels of its predecessor, which ap peared in last week's issue, is, that the two i processes of which they treat are still more closely connected and are also close at hand. A good dry-house is not an expensive struc ture, and when not used for drying hops is available for various other purposes. A build- ' ing covering a spaco of 18x30 feet, nnd hating 10 feet poslB, will bo sufficiently largo for a hop yard of ton acres. The lower story, divided t into two apartments of equal sizo, will form tho storo-room and the press-room, where the baled hops can be storoa. Tho upper story, divided in tho same way, will form tho kiln over the storo-room and tho store-room for i impressed hops. Let the building be as tight us n good outsldo boarding and iusido colling will mako it; for air and light should bo pretty effectually excluded. About two foot may bo taken from tho bight of tho kiln nnd added to that of the stove-room. This will more effectu ally concoinrnte tho heat in tho kiln, and tho floor bolng olevatod above that of the store- I room it will add to the convenience of shoving 1 tho dried hops from tho fjrmcr to tho latter. In placo of n floor between the stovo nnd kiln rooms, hoavy wiro cloth should bo placod upon tho joists; nud ovor this baling cloth should be spread to prevent tho hops from sifting through. I No glass windows should bo placed In nny of tho rooms, with the exception of that in which the hops nro prcssod, ns tho hops should be kept from tho light as much as possible. Ono window with shutters that tit closely and that can be readily managed is all that is needed for tho othor three rooms: thoush tho stovo-rootn should havo ventilutors near tho floor, which I mny bo opened or closed ns moro or less bent is required. There should bo no entrance to tho stovo-room oxcopt through tho proas-room; I and tho window through which tho hops, when brought from tho yard, nro emptiod into tho kiln, is nil tho communication nooded botweou this room nud tho outsldo world. A platform under this receiving window will bo needed iu placing tho sacks of nowly picked hops from the wagon into tho kiln. Iho dried, uubalcd hops being extremely bulky, it is desirable to have ns much spaco ns possiblo In which to store them, ns baling can not bo well nttendod to during tho drying son sou. To gain spaco for this storago, a foot or oven more mny bo tnkon from tho room i beneath tho press-room by placing tho divid ing lloor tlniB much lower. The press-room should bo woll lightod, ns it is horo that tho sowing of thu baios is dono; nnd, when the drying season is past, this room furnishes n good shop for the farm. Near tho centor of , tho room a hole nbout two feet squaro should I ba loft, undor which tho press is to bo placed, 1 nnd from which tho hops nro poured into tho press through n cloth hopper. This can bo done with a trap door, and opened as tho press is to ba filled. Ouo ot tho largost sizo box stores will answer for hop-drying, through a regular hop stovo is mado for this purpose Lot Iho plpo run un to within about two ftot of tho floor abovcJ men entering a "i, irom oacn eiul ol wmen a pipu runs around each sido of thu room enter ing tho chimney on tho sido opposite thnt at . which tho stove is placed. An earthen floor for tho stovo-room is preferable. Iu plaoiug hops within tho kiln for drying, ' ba careful nud not trample them. Havo them lay up as looso as possible, llegin in tho part of thu room most distant from the receiving door, placing them about you, nud crowding yourself out of tho room, by the Increasing surface of hops. Tako a light rake, aud mako tho surface smooth us you extend it. About sixteen inches is n good depth to spread tho hops. When the mipnly is complete, close the rcctivlng door or window, also that which lends Into the stove-room, nud tho " batch " is ready to have tho heat applied. Tho drjer must not expect to remain n longer lime iu tho stove-room than is necessary iu miking thu tires, llo should, however, give this duty his close attention, ns a uniform heat is desirable. All experienced dryer will bu nblu to catch a few minutes' shop occasionally, between thu lire-makings; but as a genornl rule tlio dryer should not trust himself iu this lespect. The stovo should bu kept nt such n heat ns will show spots of red on its surface nearly nil the tlmo.

I'ndor ordinary cirenrastnnces, ten hours' time is huUlcIe.nl for drying a batch of hops, Thu dryer, commencing his fires nt six o'clock in tho evening, will be able to retire nt four iu ' the morning, leaving everything tightly closed. About nine o'clock tho kiln should be visited, when they will bu found to ba partially cooled. Thoy should now bo thoroughly stirred, by walking through them, scraping thu ftot along the lloor, instead of stepping, thus plowing them up and bringing the bottom hops to the surface. They can again bo closed tightly, and left until such time iu the afternoon ns you wish to prepare for another drying ; then they should be shoved into tho store-room.

Concluded, The quantity seems enormous, and almost staggerers belief, but such is tho velocity with which tho machines are driven, and the multi plication of the sticks so rapid, that there is no difficulty in producing the numbor stated. When the wheels are in motion, the sticks fall from the cutters in a regular shower, and are caught in a trough below, through which passes a belt or elevator, which carries them to a se ries of machines, called shakers, with Bmnll latticed bottoms, in which thoy nresubjeotedto a violent shaking as they pass through. This operation is for the purpose ot removing all im perfect sticks and pieces of shavings. As they pass through, they aro deposited iu large cases ready to bo carried to the drying rooms. These rooms are three in number, each fourteen by fourteen feet, the floors of which are covered with n series of steam-pipes. The boxes con taining the sticks havo latticed bottoms, nud aro placcdupon theso plpos in tiers, ono nbove the other, four or five deep, when the heat is forced through tho ontiro mass. Here they nro allow ed to remain for a day and a night, subjected to a temperature of 120 degrees, which effectually dries tho wood, rendering it almost as light ns a feather. As great caro must bo used to guard against fire in thoso rooms, perforated pipes, with an independent connection, aro liberally provided, through which a sufficiency of steam can be forced in a moment to extinguish flro in case of combustion. Afior going through the drying procoss, the sticks aro carried to another sories of shakers. Hero, by an ingenious ar rangement, tho sticks, as tney nre shaken up by n livoly motion, aro straightened, when they nro doposlted in metal boxes nt tho lower end of each machine, with circular bottoms. These boxes aro made to hold as many sticks ns can be grasped by tho hand, from whence tbeyare taken, and packed in cases ready for shipment to the finishorg, who apply the com pound to tho tips. After tipping, tho matches are placed in boxes for sale. Tho plain match stick may he looked upon as an insignificant item nt first sight, but n moment's reflection will convinco tho reader that an enormous quantity is required to supply tho daily con sumption. Tho making of theso match-sticks is a distinct mnnufacturo, tho nintch-rankors in inrgo cities purchasing the sticks for tipping. The American Match-Stick Company, at Wii liamsport, Pa employ tho process described above, aud when fairly under way, expect to mako and ship a full carload of match-sticks per day to their various customers. It is esti mated that in Europo nud tho Unitod Stntos, the amount of wood annually consumed in the manufneturo of match-sticks is, nt the lowest calculation, four hundred thousand cubio yards. Ouo of Do Howons' machines, requiring three horse-power to drivo it, will, it is claimed, cut in ten hours fifty-two millions of niatch-stioks. This machino is nlso olnimod to consume less lumber by ouo half than that consumed for tho samo number of sticks by any other machino yot invented. Journal oAjjlUd .Science. An Architectural Infliction. A few yo.us ago tho monotonous stylo of roof used iu architecturo was agreeably varied by tho introduction of what is kuown as the Man sard roof, sometimes called the French nttio. kTho splendid architectural piles iu Paris re- etivcu somo oi tueir uest graces ol expression from the handsome sky-lines the Mansard roof g.ivo them, nnd almost overy American traveling abroad wondered why so graceful a roof could not bo adopted lu our Amcrloan cities, where tho large buildings usually terminated with nn abrupt, sharp, and unpicturcsquo sky-line. Tho Mansard roof nftor n tlmo wns Introduced, nud its peculiar beauty soon mado it very po pular. Hut, liko nil fashions which become thu rage, aud which nro adopted by people imitativcly, without perception of tho principle that governs them, tho French nttio hnsbocomo with us nn architectural infliction. Tho Man sard roof was designed for tall buildings. Its special purposo is to bronk tho monotony of a massive pilo, nnd to roduco iu nppenranco its real bight. A structure that would seem awk wardly tall, with nn unvaried succession of stories, has not only, by menus of tho Mausard roof, n uioro graceful caption, but nttnlus more ugreenble proportions. Tho specific purposo of this roof being rccoguized, tho absurdity of its itto in small buildings becomes nt onco appar ent. Our builders, however, seem to lack all power of perception, and to havo reduced tho art of architecture to indiscriminate imitations. Everywhere now tho Mausard roof confronts us. Every new cottage on tho roudside, now cheap villas iu those extemporized villages that Hue our metropolitan railways, new publio buildiugs of ovory sort nnd degree, rnilrond station-houses all over tho country everything of tho kind now, no matter if onlyn story high, must hnve its Mansard roof, with entire disre gard ot fitness or propriety. Il is exasperating to see n good idea thus dragged into absurd and iguoblo uses. As wo nt first hailed with pleasure tho appearance of tho Mansard roof, we shall now look with hopo for tho signs thnt will indicate tho termination of its career. Aud yet whatever may follow will have to undergo the same experience. It is our natural way to try nud appropriate) overy big thing for every little purpose. dnirrleilii JfuiMrr. Incomiii'stiiilr Wood. Severn! attempts have been made at ditl'erent times to render timber uniutlammable. A new nnd apparently successful method has recently been tested, of which, perhaps,' the most convincing of the first series of experiments was that iu which a large heap of the prepared timber, about two feet high and seven or eight feet in circumfer ence, placed ou large iron sheets, was saturated with paraffin and sot ou tiro. As soon as tho puratiiii was consumed the fire spontaneously weut out. The timbor was theu examined, and fouud to be scarcely injured. The pieces of wood were of various sizes, the majority being about eighteen inches long by two and three iuches square. Not only does the process ren der timber uniutlammable, but it has the not less important property of making the softer kinds of timber (.such ns white and yellow pine) throughout, both in appearance and hard uess, like teak or oak. What adds immensely to the value of the discovery is that the system cu le applied by a simple method to ships already built, so as to render those containing iucipient dry-rot almost as good as new, and absolutely arresting nny further damnge from must ufBiruciive uiugi.
