In brief the treatment consists of tarring the seed as is often done 

 to keep crows from feeding upon it. The seed was then placed in a 

 bucket containing fine dust and Paris green mixed in such propor- 

 tions that the corn, after being shaken up in the bucket, showed a 

 greenish color. The corn thus treated fed properly through the 

 seeder and in every case came up satisfactorily, while check rows 

 were badly injured. Examination of some of the corn thus treated, 

 after about a week, showed that the wireworms were present close 

 by the seed but that they did not molest the seed itself, apparently 

 being repelled rather than destroyed by the treatment. It was evi- 

 dent that the germination of the seed was not affected, and it is prob- 

 able that the Paris green was present in sufficient quantity to prove 

 a fatal dose for crows which might attack it. 



Soaking the seed in strychnine and other poisons gave far less 

 satisfactory results than the one just given. 



Further experiments may perhaps develop defects in this method, 

 but none have as yet appeared, and it seems desirable to test it on a 

 large scale in different parts of the country. 



FUMIGATION, DOSAGE AND TIME OF EXPOSURE 



By J. L. Phillips, Blackshnrg, Va. 



The fumigation of nursery stock was begun in this state under the 

 direction of Mr. W. B. Alwood in the fall of 1896, and soon came into 

 general use in the Virginia nurseries. The fear of San Jose scale 

 was felt very strongly during the first years of this work, and if 

 nurserymen noticed injury from the use of this gas, our attention 

 was not called to it. In fact, a number of nurserymen left their 

 nursery stock exposed to the gas from 8 to 10 hours without noticing 

 any ill effect. 



A number of lots of nursery stock, infested w4th San Jose scale, 

 were fumigated during these early years and examined the following 

 summer without finding any living San Jose scale, and nurserymen 

 and entomologists alike appear to have settled down to the conclusion 

 that fumigation is effective, and that no injury need be expected if 

 dormant nursery stock is fumigated according to directions usually 

 given. 



Of course every one recognizes the fact that for fumigation to be 

 effective it must be conducted under the supervision of careful, in- 

 telligent men, who will carry out the directions in detail. Human
