[ames, Minn. 



Saranac Inn and the Vermont nursery 

 at Burlington. The plots used were lo- 

 cated in seed beds twelve feet long and 

 four feet wide, each bed being divided 

 into three equal parts, four feet square. 

 The chemicals were used in fine pow- 

 ders, or in solutions, according to their 

 original form and nature. The solu- 

 tions were applied with an ordinary 

 sprinkling can, while the powders were 

 sifted on the beds with a very simple 

 form of duster, having a perforated bot- 

 tom, through which the powder was 

 shaken. The solutions were applied to 

 the soil before the seeds were sown, and 

 then again about five days after the 

 seedlings had come up. The powders 

 were applied to the beds only after the 

 seedlings had been up for three or four 

 days. They were applied in very light 

 coatings, which were renewed promptly 

 after each rain. "This renewal," says 

 Mr. Spaulding, "is not necessary except 

 for a period of about two weeks, begin- 



ning three or four days after germina- 

 tion, when the seedlings are most sus- 

 ceptible to the attacks of the damping- 

 off fungi."' 



Sulphur was used in three forms, 

 washed, resublimed, and precipitated ; 

 all of which gave favorable results, but 

 the washed sulphur gave the best. 



Dry Bordeaux Mixture was discard- 

 ed because of the time required for its 

 preparation. A mixture of one pound 

 copper sulphate to ten pounds of lime, 

 quickly prepared, proved equally ef- 

 fective. The lime should be slaked with 

 as little water as possible, to obtain a 

 fine powder. The powdered lime should 

 be screened, and the ingredients thor- 

 oughly mixed. 



Experiments with potassium sulphid 

 and permanganate were devoid of re- 

 suhs because of the absence of the dis- 

 ease from the plats treated. The use of 

 formalin was disappointing. 



The best results were obtained with 



European Larch, Scotch Pine, Austrian Pine, and Black Walnut, Mr. D. Hill's Farm, St James, Minn.
