peas by storing them in air slaked lime at the rate of one part lime to 

 two parts peas by weight; at least, until something more effective 

 and something cheaper and simpler can be devised for the average 

 farmer. 



Vice-President G. A. Dean: Is there any discussion? 



Mr. G. W. Herrick: Just how were the peas treated? Was the 

 lime put on and simply shoveled over and over? 



Mr. Z. p. Metcalf: We simply took air slaked lime and poured over 

 the peas and then we put them back into the sacks, no attempt being 

 made to mix the lime thoroughly with the peas. 



Mr. G. W. Herrick: Did you moisten the peas? 



Mr. Z. p. Metcalf: No. 



Mr. R. a. Cooley: How soon after harvesting were the peas 

 treated? 



Mr. Z. p. Metcalf: In this case they were treated in December. 

 Better results would have been secured if they had been treated in 

 September directly after harvesting. 



Mr. W. E. Hinds: I am very much interested in this matter because 

 it is of great importance, especially to the Gulf States. One point in 

 connection with the treatment by carbon disulphide that interested 

 me particularly w^as the serious injury to germination that resulted. 

 I have heard from other sources of serious injury to peas from carbon 

 disulphide treatment and would like to mention one series of experi- 

 ments made at Auburn, Alabama, last year. Several varieties of 

 cow peas were submerged in liquid carbon disulphide for periods 

 ranging from approximately a minute to a thousand hours with 

 absolutely perfect germination in all cases. The tests that we have 

 made show that these differences are due to the varying percentage of 

 moisture in the seeds at the time of treatment. Dry seeds were 

 uninjured. 



Mr. Z. p. Metcalf: I did not intend to state that peas treated 

 were injured by the carbon disulphide. They were injured by the 

 weevils. The weevils kept right on laying eggs after we treated them. 

 We had to make continuous applications. • I do not think that there 

 was any injury by carbon disulphide. 



Vice-President G. A. Dean: The next paper on the program will 

 be read by Mr. W. C. O'Kane.
