Herd No. 15 contains two cows which gave practically the same amount of milk and fat, yet one gave a much larger profit than the other, due to difference in feed cost.

A PROMISING YOUNG BULL AT THE HEAD OF HERD No. 21 Norfolk-Middlesex Dairy Improvement Records. On the following pages will be found the records of the Norfolk-Middlesex Dairy Improvement Association. The figures are year totals for the different cows complet- ing a full year's test and are taken from the report of the tester, Mr. R. F. Johnson, with- out verification. They represent a statement of the feed cost for the cows, but do not include charge for labor, taxes, interest, depreciation, etc., which properly come into a complete statement of the herd for the year. Apparent discrepancies in value of milk are due in many cases to cows freshening when price of milk was fluctuating. In studying the data, close attention should be paid to the price of milk, as there is a wide variation in the amount received by the different men, and unless this is taken into account the relative value of cows or methods of handling cannot properly be judged. 18
