The life history of this fungus would suggest the application of 

 some chemical, by the spraying pump, early in the spring before 

 the leaves start, to kill the spores as formed, and prevent them 

 attacking the young fruit and leaves. 



Mr. Goff of the New York Experiment Station has tried spraying 

 the trees early in the season with a solution of one pound of hypo- 

 sulphite of soda to ten gallons of water with encouraging results. 



Prof. Scribner suggests for trial the following treatment: 



(1) Spray the trees early in the spring, before the buds start, 

 with a solution made from one pound iron sulphate (copperas) and 

 one gallon of water. 



(2) After the fruit sets, spray again with Bordeaux mixture pre- 

 pared by dissolving sixteen pounds copper sulphate (blue stone) in 

 twenty-two gallons of water. In another vessel mix thirt}' pounds 

 of lime with six gallons of water. After the latter cools, pour the 

 two preparations together and thoroughl}^ mix them. It is best to» 

 prepare this mixture several days before it is needed, and stir it 

 well before applying it. If the season is cold and damp, a second! 

 application should be made, later in the season. The spraying 

 pump used to apply copper solutions should be made with copper or 

 brass fittings. 



To determine whether the spraying does good, the application 

 should be made onl}' to alternate trees in the row, or to one side of 

 each tree. The effects upon the trees can thus be readilj- compared 



RECENT INVESTIGATIONS. 



The Department of Agriculture at "Washington tried many exper- 

 iments on fungicides the last season, to be considered in Prof. 

 Galloway's report, which promises to be of unusual interest. Prof. 

 Gallowa}' has kindly sent us advance sheets of his Report from 

 which we condense the following : 



The past season experiments upon apple scab were conducted, 

 under the auspices of the United States Agricultural Department, 

 in Michigan and Wisconsin by Professors Taft and Goff. They 

 experimented with various chemical compounds as shown in the 

 table below, but the copper compounds were so much superior, they 

 alone deserve consideration. It is recommended to spray as soon 

 as the buds begin to swell. They sprayed seven times during the 

 season, but think four or five times in ordinary seasons would be
