On the market price of the ingredients of feeding stuffs. — The author 

 compares the market prices of couceiitrateil feeding" stuffs, as cottou- 

 seed aiul linseed meal, with those of the mill products aud corn. IJe 

 states that ''in our ordiuary mill feeds, carbohi*drates cost as much as 

 albuminoids," aud jj'ves iu support of this the following statement of 

 the average cost of food ingredients in these materials for the years 

 1888 aud 1800 : 



[Ccuis per pound.] 



"Cottonseed aud linseed meal, gluteu meal, uuilt sprouts, and brew- 

 ers' grains seem at present to be the most economical of our concen- 

 trated feeds.'' 



The COMPAKATIVE EFFECTS f)F TEAM IMf IN UlLLS AND DKILLS ON 

 THE QUANTITY AND (QUALITY OF TlIP: MAIZE CROP (pp. 18J-101). — The 



piece of land used for this experimeut was checked off into 24 tweutieth- 

 acre plats, so arranged that there were four rows of i)lats (north and 

 south) with six })lats iu each row. Of these four rows of plats, the 

 first row received 10.7 cords of cow manure per acre; the second row 

 13.3 cords of hog manure; the third row 1,700 ])oundsof a mixture con- 

 sisting of 100 i)ounds of nitrate of soda, 80 pounds of sulphate of 

 ammonia, 80 pouuds of dried blood, llio pounds of cotton seed meal, 90 

 l)ounds of dissolved bouebhick, and 10 pounds of muriate of potash; 

 and the fourth row received no fertilizers. Corn was planted on the 

 first, tiiird, and tilth i)lats in each row of plats, in drills 4 feet apart and 

 with the stalks 10 inches ai)art iu the drdls, and on the remaining plats 

 iu rows likewise 4 feet apart, the hills being in different series of plats 

 from 10 inches apart with four stalks in a hill, to I'O inches apart with 

 two stalks in a hill. 



"This arrangement of tiie field and fertilizers inakes possible a com- 

 parison of the relative effects of planting in hills and drills on plats 

 (pjite different as far as manuring goes, but otherwise believed to be 

 (|uite uniform in (juality. * • * In 1888 and 1889 this land had 

 received very considerably more of both potash and phosi)horicacid than 

 had been removed in the crops of those years, but on tiie other hand 

 the crops had removed some 00 pounds more of nitrogen from the soil 

 per acre than had been replaced." An excess of seed was planted and 

 the plants thinned out to the desire<l distances. The phmts were all 

 cultivated at the same time and in the same manner. 



When harvested, "each croj* was weighed and sampleil from an area 

 of one fortieth of an acre taken from the center of each plat.'' Analyses 

 were made of the kernels and stover from each i»lat, wliich are giveu iu
