of albuminoids. Leaving the water out of account, the dry 

 matter of the flesh of apples contains 1.43 per cent, of albu- 

 minoids, while the dry matter of potatoes has 8.54, and pump- 

 kins 17.32 per cent, of albuminoids. From these facts two 

 interesting conclusions are to be drawn. First, the small 

 amount of nitrogen explains at least one reason for the low 

 value of apples for feed and for manure; and, second, to 

 make economical fodder from apples or pomace, food rich in 

 nitrogen should be added. In this way not only the sugar, 

 but also the pectose, of which apples are largely composed, 

 may be economically utilized as food. Bulletin Bussey In-

THE TASTE OF TURNIPS IIS" MILK AND BUTTER. 



It is Stated, upon German authority, that the unpleasant 

 taste imparted to milk and butter by feeding turnips, etc., 

 may be removed by simply throwing into each pan of milk 

 of four to five quarts as much saltpetre as will lie on the 

 point of a knife, when a gelatinous mass will separate from 

 the milk and settle to the bottom. 9 C\ XIII., 107. 



PRESERVATION OF HOPS. 



Exhaustive experiments have demonstrated that hops, 

 packed when fresh by means of a hand-press in strong, suit- 

 ably constructed metallic boxes, and sealed up hermetically, 

 can be preserved in any cellar with a temperature not above 

 48 or 50, without manifesting the least inferiority to fresh 

 hops in color, odor, or weight ; and the beer made with them 

 in summer is said to equal winter beer in flavor and fineness.

NEW FERTILIZING MATERIAL. 



Cabien recently called the attention of the Paris Academy 

 of Sciences to the hitherto entirely neglected source of fertil- 

 izing material in tlie deposits left by every ebb-tide. He 

 asserted that, after the detritus had been suitably ground, 

 he obtained a powder consisting of calcareous phosphates, 

 which, when mixed with an equal amount of liquid and solid 

 fecal matter, aflbrded a manure containing 30 per cent, of 

 easily soluble phosphates, 20 per cent, of nitrogen, and only 

 12 per cent, of insoluble ingredients, being as rich in nitrogen
