fumigated 12,000 Bubach, Excelsior, and Johnson's 

 Early strawberry plants. These had been packed in 

 moss while en route from the nursery for nearly a 

 week, but were in good condition. About 4,000 

 Tennessee Prolific just dug were also fumigated. The 

 roots were cut back and fumigated in lots of 1,500 to 

 2,000 for ten minutes with two-tenths (0.2) grammes 

 cyanide per cubic foot. The plants were set at once 

 after fumigation and were not watered. They made a 

 good stand, very few dying so few that there was no 

 question that the gas had done no injury, as two check 

 rows were left which made no better stand. April 2oth 

 over 10,000 Bubach plants were fumigated. These 

 had been dug for one or two days and packed in a 

 barrel. They were quite wet when fumigated. About 

 8,000 were fumigated with one-tenth (o. i) gramme 

 cyanide per cubic foot for ten minutes, and i ,500 at same 

 dose for fifteen minutes, while nearly i ,000 were planted 

 unfumigated as a check. After these plants were fumi- 

 gated they were aired five minutes, roots dipped in 

 water, and repacked in barrels. They were set. out 

 three days later. The plants showed no injury from 

 the gas, all making an equally good stand. 



In the experiments of Professor Sanderson the 

 earth was firmly packed around the open bottom of the 

 box used. The plants were well cleaned of earth, laid 

 on trays, the bundles being cut open and thoroughly 

 loosened. The lid of the box was then closed and 

 fastened. A coffee cup or similar vessel was placed in 

 the lower corner of the box by the door, and into it was 

 first dropped a vial containing a proper amount of the 

 cyanide in solution. A vial containing the sulphuric
