dried in the sun. The seocls did not dry thoroughly and tended to 

 adhere to one another. This would be a great disadvantage, as it 

 would be hard to run these treated seeds through a planter. The 

 following summary further shows its impracticability:

WHALE-OIL SOAP. 



The seeds used in the whale-oil-soap experiment were treated in 

 two different ways. At first they were coated with the soap, but 

 this method proved impractical (1) because the seeds could not be 

 used in a planter and (2) because they tended to rot. The seeds 

 were then treated by soaking in a concentrated water solution of the 

 whale-oil soap. This second method overcame the objections to the 

 first method. The results are summarized below.

This table shows that the treatment of the seeds with whale-oil 

 soap holds little promise of success. 



TAR WATER. 



Since satisfactory results in seed ])rotection by coating the seeds 

 with tar have been reported, it was thought possible that similar 

 results might be obtained by soaking the seeds in tar water. In 

 this way it should give the benefits of coating the seeds with tar,
