BARLEY AND WHEY FOR PIGS. 



For some years we have known that harley was a good i>ig feed, 

 and urged its raising for that ])urpose. Barley makes a very good 

 nurse crop for lucerne or clover, and its splendid feeding qualities for 

 both swine and cattle make it a desirable crop. 



The recent reports of feeding experiments carried on at the Wiu- 

 eonsin experiment station show barley to be somewhat more valuable 

 than maize. We had held until this experiment was conducted that 

 maize was a little superior to barley, although we knew the Danish 

 farmer valued barley a little higher than maize for feeding swine. 



We were also surprised to note that the pigs receiving barley and 

 whey did better than those receiving tankage and maize. We aj)- 

 preciated thatVhey contained 0.8 per cent, albumen, but did not think 

 that sufficient to supplement either barley or maize and make it a 

 suitable ration for producing swine economically. 



The pigs receiving barley and Avhey charged £1 13s. lid. for each 

 100 lbs. of gain made, calculating barley at farm prices, which was 

 3s. 6d. per bushel, and estimating 100 lbs. of whey at one-fourth tlie 

 price of a bushel of corn. The whey was actually worth Is. 9-|. per 

 100 lbs., compared with tankage at £22 18s. 4d. per ton. Compared 

 with middlings at £9 3s. 6d. ])er ton, AVhey was worth 2s. Bid. 

 per 100 lbs. 



It should be borne in miud that not all ])rotcins are ca])al)le of 

 producing good growth. Protein is made up of several substances 

 called amino acids. Some have termed them building stones. A grain 

 may have only fifteen of these building stores, and the problem of the 

 feeder is to supplement the other three, as a perfect protein like the 

 protein of milk contains eighteen. It is, therefore, plain that some 

 feed containing these amino acids, Avhich are lacking in grain, i>; the 

 one to supplement the feed to make the largest gains. 



Farmers taking their milk to the cheese factory may seriously con- 

 sider a ration of ground barley and whey for swine. In the northern 

 part of our country w^here maize is not a sure crop, barley can he 

 grown, and when supplemented witli either whey or skim-milk produces 

 fine pork. — Kimlmll's Dairy Farmer.

The Orchard. 



As a preventive against codlin moth, apple and pear trees should be 

 sprayed with arsenate of lead whenever there is danger from the 

 prevalence of the moth. One of the secrets of success in codlin moth 

 spraying is the destruction of as many as possible of the insects of the 

 first brood. Thus, if particular care is given to the early sprayings, 

 keeping the fruit covered with spray fo,r a month or six weeks after 

 setting, this result is easily accomplished. Some growers prefer to
