New York Agricultural Experiment Station. 301 



In a 4 per cent solution 1.5 hours gave 0.1 per cent and was not in- 

 jured. Tlie 4 per cent treatments, where seed was soaked 0.5 hour 

 and 1 hour, prevented smut without injuriuig the seed. 



EXPERIMENTS AT TRUMANSBURG. 



Since the experiments at the Station were of necessity con- 

 ducted on small plats, it was deemed advisable to duplicate a 

 few of them on a larger scale in a locality where the oat smut 

 was abundant the previous season. Accordingly, arrangements 

 were made with Messrs. King «fe Robinson, Trumansburg, Tomp- 

 kins county, by which a plat of two-sevenths of an acre was used 

 for each different treatment. 



On April 13 the seed was treated by sprinkling in lots of one 

 bushel as follows:

Method of Treatment. 



The oats were placed on the barn floor in piles of one bushel 

 each. The necessary amount of each chemical was put in one 

 gallon of water and was applied with a sprinkling pot. By spread- 

 ing the pile somewhat and alternately sprinkling and turning 

 the oats, each bushel was thoroughly saturated and absorbed 

 practically the whole gallon of the mixture. To dry them the 

 piles were spread and shoveled over occasionally for two or three 

 days. 



Seeding and Growth. 



The seed was drilled in April 21 at the rate of two and one- 

 fourth bushels per acre. Three check or untreated plats were 

 sown for the five treated plats. The seed treated with Ceres 



♦This strength is at the rate of one ounce in one gallon of water, practically as per 

 directions of the manufacturers of Ceres powder, who recommended one' ounce of the 

 powder in one gallon of water sprinkled on 33% pounds of seed.
