and Mr. C. C Giddings' vineyard near Lawton. The work in ]\Irs. 

 Smith's vinej^ard was conducted on the same plats used in 1907 and 

 with the same spraying outfit, and as before trailers with nozzles di- 

 rected by hand were use instead of fixed nozzles for the last three spray- 

 ings. It was found that in order to satisfactorily cover the foliage and 

 fruit, at the time of the later spraying the nozzles, or part of them at 

 least, must be thus manipulated. 



The treatment given Mrs. Smith's vineyard, is shown in the following- 

 tables :
