 market prices for dicssed pork can bo secured. The quality of the meat is also ai)t 

 to be impaired by a«i increased doposirion of fat. The power of assimilating food 

 and of converting it in an economical way into an increase of live weight, decreases 

 witli the progress of ago. 



(5) It pays well, as far as the cost of food is concerned, to protect the animals 

 against the extremes of the season. Feeding experiments carried on during moder- 

 ate seasons are nu)re profitable than those carried on, under otherwise corresponding 

 circumstances, during the wiuter season. 



Fodder analyses, 0. A. Goessmann, Ph.D. (pp. 124-147). — Analy- 

 ses of the following: feeding stnffs, made during the year (1889) are 

 given : corn meal, wheat bran, gluten meal, old and new-process lin- 

 seed meal, " fine feed," barley meal, white soja bean, black soja bean, 

 soja bean (entire plnnt), corn husks or chaff, corn germs, low meadow 

 hay, corn stover, silage, barley and oat chaff, Spanish or long moss 

 {Tillandsia usneoides), palmetto root, and samples of corn, together 

 with tiie fertilizing ingredients of the new and old-process linseed meal, 

 l)la(;k and white soja beans, soja bean (entire plant), barley and oat 

 chaff, Spanish moss, palmetto root, and corn (kernels). 



In presenting these analyses, it seems but proper to call the attention of farmers 

 once more to a careful consideration of the following facts: 



The composition of tlie various articles of food used in farm practice exerts a 

 decided intluence on the manurial value of the animal excretions. The more potash, 

 phosphoric acid, and in particular, nitrogen, a fodder contains, the more valuable 

 will be, under otherwise corresponding circumstances, the manurial residue left 

 behind after it has served its purpose as a constituent of the food consumed. * » » 

 The higher or lower commercial value of the manurial refuse left behind decides the 

 actual or net cost of a feeding stuft". * * * 



It needs no further argument to prove that the relations which exist between the 

 composition of the fodder and the value of the manure resulting deserve the careful 

 consideration of the farmer.

(1) Iii/iueuGe of nitrogen on the yield and general character of the corn 

 crop (pp. 148-155). — A report is given of an experiment with corn on 

 11 tenth-acre plats, all of which received like amounts of potassium 

 oxide and ])hosphoric acid, and 7 of which received either dried blood, 

 sulidiate of ammonia, or nitrate of soda in amounts furnishing the 

 same quantities of nitrogen. Three plats received no nitrogenous fer- 

 tilizers, and one received barn-yard manure. Data are given relative 

 to the height of the crop at different dates, the yield of stover and 

 ears, and the percentage of well developed and undeveloped ears on 

 each plat. The crop on the plats receiving no nitrogen was of a light- 

 green color, and "dining the first half of the season the same feature 

 was noticeable to some degree on the plats receiving sulphate of 

 ammonia. Upon the remaining plats the color was deep green, indica- 

 ting a vigorous growth. * * * iN'ot less noticeable is the difference 

 in the character of the hnal crop. Those plats which received no nitro- 

 gen in the fertilizer applied produced not only by far the smallest
