CREAM FROM MILK OF OUR GUERNSEY COW, BY 540 DIAMETER.

Lizzie.

Beckie.

Worthy Beauty.

Analysis No. I, of March 19, represents the composition of the morning milk of one Guernsey cow with fourteen months calf. The cow was about six years old. (Born April 11, 1878.)

Rosetta III was born December 8, 1881; dropped heifer calf April 5, 1884; served April 26, 1884.

On May 17, 1884, the date of analysis No. II, her feed was four quarts corncob meal and bran twice a day, with about one half bushel of green rye and hay at each feed. The feed on December 27, analysis No. III, not known.

Analysis No. V represents the composition of milk of cow Lizzie, owned by A. Scott; dropped calf five and one half months previous to date.

The cow Monoca, from which the next sample was taken, calved four weeks previous to date of analysis. The milk was taken from each of these two cows at eleven, A. M., and was the mixed milk of two teats, one hind and one front; the cows had been milked at five, A. M. The feed of each cow was four quarts cornmeal, eight quarts bran, one pint cotton-seed meal, with hay, corn fodder, and wheat chaff, all mixed together. In addition to the above feed, each animal received some timothy hay twice a day. Weight of each cow, nine hundred and fifty pounds.

Samples VII, VIII, and IX were from the milk of three cows named in the table, owned by Thomas M. Harvey of West Grove, Chester county, Pennsylvania. No data concerning the history or feed of the animals was given me. The cows furnishing samples No. X and No. XI are the property of Henry Palmer of West Grove; the one from which sample No. X was taken dropped last calf May 31, 1884, and was last served August 2. 1884.

On January 21, the milk of the two Guernseys, Monoca and Lizzie, owned by A. Scott, was again analyzed. The feed was the same as on December

22, except this time the cows had clover hay instead of timothy.

The history and feed of Beckie, whose milk was analyzed on July 13, is as follows: Age, five years; calved four months previous to date; feed, eight quarts bran, with pasture; property of A. Scott.

The ten cows furnishing the milk of the next analysis were also owned by A. Scott. The feed of each cow was eight quarts bran per day, with pasture.

The next analysis is also of the milk of a cow three years old, with first calf, owned by A. Scott; feed, eight quarts bran per day, with pasture. The cows furnishing milk for analyses XVII and XVIII were owned by Thomas M. Harvey. The following letter gives a complete description of condition of animals, mode of obtaining samples, feed, &c.

Milk (Thoroughbred Guernsey),

(Sent to Prof. C. B. Cochran, West Chester Normal School, July 14, 1885, by Thomas M. Harvey & Son.)

Following conditions:-Cows on dry pasture-plenty of flies and in addition, most of the cows have about two quarts of wheat-bran each, morning and evening. We report the whole milk for each cow for twenty-four hours; samples taken from morning's milking.

The whole milk-eight pounds-was taken from Worthy Beauty, and then poured six times back and forth from one bucket to another, then a pint of the milk dipped out. Immediately, a three-ounce vial, filled without stirring, to use in photographing (in case the stirring spoiled the other samples for that use), and this vial was at once put in ice water. The bal

ance of the pint was then stirred twenty minutes, vessel setting in ice-water; at the expiration of that time, a four-ounce vial was filled from it and corked up for analysis.

After this, six other cows of different ages and conditions were milked, each weighed separately, and then thrown into one vessel, and after this from one to another vessel six times, until thoroughly mixed; then a pint dipped out and stirred twenty minutes in ice-water, as the other sample; and then a four-ounce vial filled, corked, and sent off.

The following are three analyses of the milk of Devon cows, property of Dr. Cheston Morris:

On March 26, the feed was cornmeal, hay, and cut fodder twice a day, one bushel of potatoes once a day.

On May 3, the feed was two quarts corn-cob meal and hay twice a day, for each cow, two bushels of potatoes daily, for the nine cows on grass for a week.

The following tables represent the average composition of the milk of three breeds of cows as accurately as it can be obtained from the data furnished by my analysis.

In the case of the Devon milk, I have taken only the average of the two analyses of the milk of the nine cows, and in the case of the Friesian and Guernseys only the average of the analyses of the mixed milk of several

animals.

The table showing the composition of Jersey milk is given in another part of this article, and is on the authority of Prof. Cock. As my own analyses were made on individual cows, I do not regard the results as indicative of the average composition of the milk of Jersey cattle.
