of Bordeaux mixture could be cleaned with a weak solution of vinegar 

 (2 quarts of cider vinegar to 10 gallons of water) at an average 

 expense of cents per 100 pounds of grapes. For this purpose Mr. 

 Anthony used the following apparatus: (1) Circular wire baskets 20 

 inches in diameter and 11 inches deep; (2) three ordinary tubs, one 

 for the vinegar solution and the others for water; (3) wire frames or 

 shelves from a fruit evaporator. The l)askets loaded with grapes 

 were soaked for a few minutes in the vinegar solution, dipped in each 

 tub of water, and exposed a short time to dry on the wire frames. 



Tests' made by the chemist of the Station indicated that grapes 

 which have been spraj^ed with the Bordeaux mixture did not have 

 enough adhering copper salts to injure health when eaten.

Notes on the black rot of the grape, M. II. Beckwith (pp. 

 28-32). — An account of experiments in Dr. Black's vineyard (above 

 referred to), with sulphate of copper, sulphate of potassium, Eau 

 Celeste, and Bordeaux mixture on Champion and Concord grapes. 

 The Bordeaux mixture produced the best results on the Concords, but 

 i'ailed to protect the Champions. The experiments will be continued. 



BULLETIN No 7. DECEMBER. 1889. 



Stock feeding, A. T. Xeale, Ph. D. (pp. 3-2-1). — 1. Utilization of 

 clover hnii and cornstalks. — It is urged that under certain conditions 

 live stock should be kept upon a farin, even if the market prices of 

 milk and meat admit of no direct visible profits. Such conditions 

 exist — 



(1) "V^^ien crude farm products, clover hay, etc., command at 

 Avholesale prices lower than their intrinsic values. 



(2) When large quantities of unsalable cornstalks, etc., are on 

 hand, which could be used as food for milch cows, sheep, etc. This 

 is supported by calculations based upon the composition of clover hay 

 and of cornstalks, the quantities and values of their nutritive ingre- 

 dients for feeding and of their manurial ingredients for fertilizers, 

 and the estimated cash value of these feeding stulfs if used in making 

 milk to sell at creameries. 



2. Explanation of terms tised in the analysis of feeding stuffs. — 

 The meaning of the terms crude protein, carbohydrates, fiber, etc., is 

 explained and illustrated by a woodcut, in colors, of a section of a 

 grain of wheat, as viewed under the microscope. 



3. The chemical control of concentrated feeds. — In 1889 twelve 

 inspectors, selected from the farmers in different sections of the State,
