Weight of ear corn per bushel of shelled corn, G. E. 

 Morrow, M. A. (pp. 450, 451). 



The percentage of water iu corn in Central Illinois when husked in the autumn of 

 1890 was considerably less than in the years immediately preceding. We have found 

 that 70 pounds for the early, 73 for the medium, and 78 for the late-maturing varie- 

 ties tested at this station was sufficient to produce a bushel of air-dry corn at the 

 last of October. 



Tests have been made February 14, 1891, in which a trifle over 65 pounds of Mur- 

 dock, an early maturing variety, 66.5 pounds of Learning, less than 67 i>ounds of 

 Burr's White, and a little over 66 pounds of mixed varieties of yellow dent made 56 

 pounds of shelled corn. The ears were not especially selected. * * * 



When thoroughly air-dry, 12 pounds of cob per bushel, or 68 pounds of good ear 

 corn for 56 pounds of shelled corn, would seem a maximum for any variety suitable 

 to be grown in this latitude. When the ears have been carefully selected, as in 

 selecting corn for seed, less than this should be sufficient. When delivered to the 

 buyer in the ear, there are often many partly shelled ears, inferior ears, some dirt, etc. 



No tixed rule can be given for determining the proper weight of ear corn for a 

 bushel of shelled corn soon after husking. The per cent of moisture in both cob and 

 kernel varies greatly iu dift'erent seasons and in difierent varieties.

Milk tests, E. H. Farrington, M. S. (pp. 453-407). 



Testsof milk of separate eoics (pp. 453-400). — The importance is urged 

 of more definite knowledge regarding the milk of each cow of the herd, 

 which the devising of various simple methods for the testing of milk 

 has placed within the reach of every intelligent farmer. The record 

 of two registered cows of the same breed is given from the Annual 

 Eeport of the Maine Station for 1889, showing wide variations iu yield 

 of milk and butter. A report is made of tests of the milk given by 

 each of fifty cows in 24 hours, being a continuation of the work in this 

 direction, reported in Bulletin No. 10 of the station (See Experiment 

 Station Record, Vol. II, p. 211). These fifty cows belonged to four dif- 

 ferent herds. Tabulated data, showing the yield of milk and of butter 

 fat iu 24 hours, date of calving, etc., are given for each animal. In herd 

 A, consisting of thirteen cows, the time since calving was iu each case 

 4 mouths. The yield of milk in 24 hours varied from 8.25 to 15.25pounds, 

 averaging 11.5 pounds; and that of butter fat from 3 to 0.G2 pounds, 

 averaging 0.46 pounds. 



The thirteen cows in herd B had all calved withiu a month. The milk 

 yield for 24 hours ranged with the individual cows from 17.75 to 68 

 pounds, averaging 25 pounds ; and of butter fat, from 0.7 to 1.25 pounds, 

 averaging 0.9 pound. In each herd the cow which gave the most 

 milk produced the largest amount of butter fat, but " the most but- 

 ter fat was not always produced by the cows giving the most milk. 

 * * * The best cow [of herd B] was 77 per cent better than the one 

 giving the least butter fat on this day, while in the previous compari- 

 sons [herd A] the best was over 100 per cent better than the poorest." 

 Wide differences were also nu Lit cable iu herds C and D, but as the time 

 since calving was less uniform the comparison is less striking.
