December, 1878. THE WEST SHORE. CARP CULTURE. From a series of articles now being printed in the Pacific Rural Prttt on carp culture, we make the following extracts on the con" traction of fiah pondi : I will give guuorai rule biutb will apply to pondi of all sizes from 1,000 acrei to one rod square, and that is in selecting a site for ponds of considerable size these points ought to be observed: 1. Is there a sufficient supply of water in the dry season? 2. Is the ground, soil and water favorable for fish culture? 3. It is important to examine the land minutely, in order to And what the components are. 4. It ought also to be deoided from the commencement now large the establishment is intendod to bo; whether only for private use and pleasure, or at whole sale for the production of the flsh as an article of trade. A rocky, gravelly ground is not good for the Union, it is necessary to ascertain whether they can be put into the proper condition for regular culture. This can only bo done if toe influx of water can be regulated and the entire drainage of the pond made possible. Trunks of trees should be taken out of then, and when they are too deep thev should hs (tiled un or a una cannot be done, they should be brought into connection with the above described as wars on the bottom of the pond. If this is not done too many Hah will remain in these holes when theDondJis drained, and this will lessen the profits to a great extant. To carry on carp culture in a regular and judicious manner, several ponds are required, according to the various purposes they are des tined for: First, the batoning pond; second, tho breeding pond, or pond for small Hah; third, the culture or regular oarp pond. A New Metal. M. Delafontaine announoea the discovery of philippium, a new metal. He has obtained from nadolinite an oxide of a really new metal, to whioh he gives the name of THK LLAMA AND ALPACA. We give on this page, pictures of two rumi nant animals whioh are agreeable and even at tractive in appearance, are inoffensive in their The wool of the llama is made Into cords and sacks, and of these again are made various tuffs; and in Msxioo the bonus are converted into instruments fur weaving the wool. Hut the European sheep is gradually taking the place of the llama, even in Peru. The alpaca inhabits the more elevated ranges of South America, living almost on the burden of perpetual snow. The Peruvians keep vast llocks of them (or their long, silky fleeces, whivh lor luster rival that of the Angora goata. The "alpaca cloth," of the dry goods trade, is made of this materu! It is principally used for woman's clothing; but is now largely used for LLAMA. ALPACA. carp culture. Ground with a considerable mix ture of loam, day and humus is good. If the size of the pond has been deoided on, the leveling of the bottom is required to assist in the determination of the depth of the ditches, collector and outlet to be dug. A ditch should run through the center of the pond, and be from two to three feet deep, and four or five wide. In ponds of considerable sise there should be cross ditches. At the lower end of this ditch there is what is called the "collec tor," whioh is a place dug out large enough to hold all the flsh in the pond. This should be one foot deeper than the ditch, and from this the sluice box runs through the dam. In the erection of the required dam it is most important that it be made of the very beat ma terial, so as to make it secure against the de structive influence of the water. It ought to be three times as wide at its base as it is high, and at the top aa wide a it is high. The in tenor, or water side, should be less inclined than the exterior one. If it be designed to make use of natural ponds, of which there are numbers in every State in " Philippine " (Pp.), in honor of M. Philippe Plantamour, of Oenevs, the friend and student of Herxeliua. Bupposiug "philipmne" to be a protoxide, its approximate equivalent Is be tween (JO and 06. M. Delafontaine describes in ths fVomaV HhvIum some properties of its for miate, sulphate, nitrate, etc. "Philippium" gives well-marked characteristic bands in the spectroscope. Oxoxi m Disease. -Dr. Beitar, in his essay on diphtheria, referring to the rapid rusting of iron in the open air as an Indlastien of the presence of osone, any: "When I have patient recovering from a severs) illness, on whom mgnniii mischief seems to nave been spared, bat tho reoopsreti ve fores appears held down by humidity and elonded iky, my (In eight of the rails of onr railways rsddsnsd with oxide 8Us nss with a bopetsl expectation of recovery where We has bean tumbling In the balance, that has rarely been disappointed.
