and after a series of trials this station advises the nsing of 15 cubic 

 centimeters of the soda solution instead of 10, and 10 cubic centimeters 

 of alcoholic soap solution instead of 5 as originally recommended. With 

 the revised method four persons, "unskilled in chemical work," secured 

 results, in several instances on the first trial, which differed on an aver- 

 age by only 0,03 per cent of fat from the gravimetric determinations. 

 The bulletin also contains an article taken from Bulletin No. 16 of the 

 Vermont Station (See Experiment Station Record, Vol. I, p. 320) on 

 systems of paying for milk at creameries in Yermont, including atable 

 for calculating the actual value of the milk as based on its fat content.

Pedigrees OF dairy animals under investigation, P. Collier, 

 Ph. D. — In view of the fact that certain strains of the several breeds 

 have had their respective claims urged ar, ])ersistently and warmly as 

 those of different breeds, the station publishes the pedigrees of the 

 twenty-seven animals under trial, " that such resirlts as we shall secure 

 in our investigation may be understood as clearly as possible."

Testing of dairy breeds, P. Collier, Ph. D. — A continuation 

 of the record, which is to be published every six months, of the trial of 

 dairy breeds commenced in April, 1889. That for the six months end- 

 ing October, 1889, was given in Bulletin Xo. 18 of this station (See Ex- 

 periment Station Record, Vol. I, page 209). The present bulletin cov- 

 ers the six months, from October, 18S9, to April, 1890. Tables give 

 analyses of the feeding stuffs, "mixed haj's," oat hay, pea hay, barley 

 hay, maize and alfalfa forage, maize silage, roots, ground oats, wheat 

 middlings, wheat bran, and linseed, corn, and cotton-seed meals; and 

 for each animal the weight and amounts of nutrients in each feeding 

 stuff consumed per day, per month, and the total for six months; aver- 

 age of the animal's weights for the last five mornings of each month ; and 

 the age in days iip to April 1. For each breed are given the average 

 gain in weight, pounds of dry matter consumed per pound of gain in 

 weight, and dry matter eaten per 1,000 pounds of weight during each 

 month of the year's trial. For all breeds taken together are stated the 

 average per animal of gain in weight, amount of each nutrient con- 

 sumed, and amount of dry matter eaten per pound of gain in weight and 

 for each pound of live weight of animal during the first and second six 

 months of the trial. Particulars as to the breeding of the heifers are 

 also given. 



The purpose has been simply to present the data thns far accumulated in such form 

 that certain of the salient points may he the more clearly seen, rather than to at- 

 tempt at this early period in the investigation anything in the way of conclusions. 

 To those vrho may desire, the data already secured will afford much material for care-
