On July 6tli, at my rc(|ucst, he kindly subinittcd a rc'i)ort of 

 the work done willi dry Bordeaux in both his nursery and 

 orchard. He sprayed a ten acre orchard of ten year old trees 

 on May 5th, May 19th and June ist, and averaged 65 lbs. of 

 dust each time. The time recjuircd for the lirst spraying was 

 four hours, and two men and one team were re([uire(l. Ilis 

 dust, consisting of a mixture of ground lime, Sal Bordeaux, 

 Sulphur and Paris Green, compomided and prepared by the 

 dealer, cost him 4c per lb. leasing my c(jm[)utations upon the 

 usual wages of men thus employed, and cost of team, the labor 

 and materia] for \\\v three sprayings, amounted to about 

 $22.50. h'roni the fact that tin's was done on an orchard, 

 whereas the spraying with liquid B)ordeau.\, cost of which is 

 given above, was done in a nursery, an<l for other evident rea-

 Mohl's own words in reply to certain questions .sent him from 

 this of^ce on July 14th.
