gradually substituted for a portion of the milk, until eight 

 quarts of the mixture and no milk are given per day. As 

 much clover and white hay as it will eat are supplied at the 

 same time. After three months only half as much of the mixt- 

 ure, is fed, with the addition, however, of about half a pound 

 of oil-cake, and in the fall of boiled potatoes also. It may 

 likewise be given to calves at first, when milk does not 

 agree with them. 28 (7, Januari/^ 1873, 18. 



REMEDY FOR COLIC IN HORSES. 



Chloral-hydrate has been highly. recommended by the Ag- 

 ricultural Central Association in Potsdam as an excellent 

 and certain remedy for colic in horses. Half an ounce of it 

 is given in a pint of castor-oil. This remedy, however, should 

 be administered with caution. 9 C, No. 3, 1872. 



PROPER LIGHT FOR STABLE WINDOWS. 



The regulation of the admission of light into stables by the 

 proper location of the windows has been found to be of the 

 highest importance. A side window, according to numerous 

 observations, is apt to produce weakness in the eye on that 

 side ; a window immediately in front of the manger throws

 over-sighted, and consequently liable to shy at low objects.

EXTIRPATION OF SILK-WORM DISEASE. 



Perfect freedom from disease of the silk-worm moth, from 

 which the eggs for a succeeding crop are to be obtained, is 

 considered of the utmost importance, since eggs from dis- 

 eased insects are sure to produce diseased worms. For the 

 purpose of securing the desired result, the Susani method is 

 now largely adopted in France and Italy. This consists in 

 placing the male and female in a little tulle bag, about four 

 inches long and two inches wide, w^hich, after being closed, is 

 hung up on a wire. After the eggs are deposited inside the 

 tulle bag, both moths soon die, and are then tfl^en out of the 

 bag, put into a mortar, and crushed to powder. Distilled 

 water is next poured on the powder, and a drop examined 

 under a microscope. If the drop appear clear, both moths
