Dr. C. D. Hunter, of Santi Hobs, hu given much attention to tho ttuily of utmosphoric and climatic phenomena in different parU of tho world. He write for a recent imuo of the Santa llota DmOtrtU an article to ahow tho philos ophy of en:nie from froeta at moderate ele vationa, while valloyt holow are badly bitten. Although all of n know practically that such ia the fact, not all are conversant with the reasons therefor, and u the subject is of interest to many who arc intending fruit growing and the like, we shall present in condensed form the atmospheric performances outlined by Dr. Hun ter. It tooeins that tho first clear demonstration that the valleys were more subject to frost than the hillsides, resulted from the establishment of meteorological stations in Switzerland. There the great hight of the mountains and the nar rowness of the valleys allow their difference much more markedly, and to as great a hight as .1,00(1 feet. Santa Hosa valley is so large and w ide in comparison to tho hight of its surround ing hills, that the difference is neither so mark ed, nor can it extend to so great a hight. Prob ably in our smaller valleys, and the great Sac ramento valley noar the foot of the higher Sierru, will lie found many low-lying grounds subject to night frosts oven late in the spring teuton. I'he main ciuso of this peculiarity in tho dis tribution of low temperatures is to lie found ill the but slight heating effect of the sun's rays on the atmosphere. I hu sun must first heat the toil, and then the soil heats the air. Con versely the cooling of the air is also effected hy the anil; and hence tho air nearest the soil is always the hottest when the sun is shining, and the cnhiest when the sun is absent, ror the same reuon the surface air experiences the gmatent changes of temperature. So it comes that the air of the valleys lieing hedged in by a turf nee of soil on every side goto rapidly heated when the nun sliiuei, whereat that of tho hills hu not only lets surface for an equal quantity of air, but it it almost constantly in motion, and each new supply keeps down the tempera tun. o( the turlace soil anil air. The glaoiors of the SierrM and the UMW-Oappad peaks of high mnimUitia even in the tropics, boar witness to the fact that tho direct rays of tho sun have but little MWM to heat the atmoonhoro ; for otherwise the higher we Mcended the warmer it should be. Few have any idea of tho extreme changes of heat cxiwrioncod by the surface soil. When the maximum thermometer in tho air will regis ter 70 or SO , one on the anil may roach 1 10 to l.'ki. Hut even More the sun sets and as its rays ceue In heat the soil, the surface rapidly MOM down, and after a calm, clear night it will lie MOM, u a rule, from 4" to 8' colder at sun n.e than the air (our feet alxive it. Now, u every one knows, cold air ia heavier than iiot air. hataM what forms m the valley remains there.

That salt will curdle new milk; hence, in preparing milk-porridge, gravies, etc., the salt should not be added until the dish ia prepared. That fresh meat, after beginning to sour, will sweeten if placed out of doors in the cool air overnight. That clear, boiling water will remove tea stains and many fruit stains. Pour the water through the stain, and thus prevent it from spreading over the fabric That ripe tomatoea will remove ink and other stains from white cloth, also from the hands. That a tablespoonful of turpentine boiled with your white clothes will greatly aid tho whitening process. That boiled starch is much improved by the addition of a little sperm, or a little salt, or both, or a little gum arabic dissolved. That beeswax and salt will make your rusty ll.it mms as clean and smooth as glass. Tie a lump of wax in a rag, and keep it lor the nor lose. When the irons are hot, rub them first with the wax rag, then scour with a paper or cloth sprinkled with salt. . That blue ointment and kerosene mixed in equal proportions and applied to bedsteads is an unfailing bedbug remedy, and that a coat of whitewash is ditto for the walls of a log-house. That kerosene oil will soften boots or shoes which have been hardened by water, and ren der them as pliable as new. That kerosene will make your tin kettle as bright as new. Saturate a woolen rag and rub with it. It will also remove stains from, and clean, varnished furniture. That cold rain-water and soap will remove machine groase from washable fabrics. Coating Metals With Tin. The process of coating metals with tin promises to extend its use for culinary and other uses. Its elo 'tin deposition is proposed by means of a zinc and carbon battery. The inner cell con taining tho lino is tilled with dilute sulphuric acid. The articles to be coated with tin art put into a bath composed of 8 parte of proto chloride of tin, Hi of cream of tartar, and 2 of the chloride if the latter is used. When it is pres ent the tin coating is effected more rapidly, whereas, when the bath ia composed of proto chloride of tin and cream of tartar only, the till coating is very white, but ia not produced so rapidly as when the chloride is used. These in gredients should be dissolved in about 100 gal ons of distilled water. The black plates art first "pickled" in any suitable manner, and then immersed in the above deaoribed bath or solution, and are allowed to remain in the tame for a longer or shorter time, according to the thickness of the deposit or coating of tin re quired on the plates. While in this bath the plates or other pieces to be coated are connected by a wire with the positive end of the battery, while the negative end of the battery is con nected with a piece of tin hung in the same bath. When the plates or other pieces or arti cles have been sufficiently coated with tin, they are held over a fire in order to give the tin a nisiroi rous appoarance. CoMrRxjwiNii Bran. Wo recently referred to j some successful experiments in compressing flour. We now learn that tome Minneapolis miller, are experimenting with machinery for comirouing bran, for the purpose of shipment I to Kurupe. It is believed that it can be to compressed at to get aa much weight into a given package aa the same would hold of floor. l'litMrHiui or oau'ICM on becoming wet will give off spontaneously combustible PBror7 ed hydrogen, thus emitting light This it th principal ingredient used in tho distress and guiding tignala thrown into tho water from a sinking ship, principally to guide those ia M water to the boat.
