Machine v. Hand Milking. 



Thk Dairy Husbandry section of the Michigan Experiment Station, in the 

 course of extensive studies in the cost of milk production, has secured data 

 regarding the time occupied in hand milking as against machine milking. 

 Records were kept of ninety-three herds, in forty-two of which hand milking 

 was pi-actised and in fifty-one machine milking. The facts can be best 

 presented thus : — 



Hours milking per cow, per year 



Care of milk and utensils per cow, per year. 



Total time per cow, per year ... 



Hours milking per 100 lb. milk 



Care of milk and utensils, per 100 lb. milk .

hours. 



Comparing large herds with small, it was found that the time saved was 

 appreciably greater with the larger herds. The tune spent in drawing and 

 caring for 100 lb. milk with machine milking, in heids of fifteen cows or less, 

 was 1-21 hours, but in herds of over fifteen cows, it was only 1-09 hours. 



Treatment for Worms in Horses. 



The following treatment for worms in horses is recommended by the Chief 

 Inspector of Stock. Put the horse on bran mashes for three or four days, 

 then starve for twelve hours, and afterwards drench with 2 oz. of turpentine 

 well shaken up in a pint of raw linseed oil. The drench should be given 

 slowly by the mouth, care being taken not to tie the animal's head up, and 

 to let it down at once in the event of coughing. 



The European Corn Borer. 



Some months ago much interest attached to the alarmingly rapid spread of 

 the European corn borer in portions of the United States and Canada, and 

 to the warnings issued about the possibility of its appearance here. Recent 

 advices of the Washington Department of Agriculture show that its attacks 

 have been confined to a limited area in the Boston district and the injury 

 there has been small. As with many insect invasions that at first look 

 most threatening, this borer largely confined its operations to a specific class 

 of feed (sweet corn and dwarf fiint varieties), and climate acted as a distinct 

 control in limiting the number of broods in cool districts to one in the season. 



It was observed that the worst infested fields were usually eithei- poorly 

 tilled and weedy or surrounded by neglected areas, and there were notable 

 examples of well-tilled fields even of sweet corn with clean surroundings in 

 which injury was negligible — so that there is a possibility of cultural control. 



An important natural enemy has develojDed in the form of a small 

 parasitic fly that destroyed fully 4.3 per cent, of the* eggs of the second 

 genei-ation ui the Massachusetts area of infestation ; in places the parasitism 

 reai'ih^d 75 per cent, of the eggs.
