THE SAN JOSE SCALE 



277 



subjected to the gas treatment Examination made a few months 

 thereafter disclosed no living scales. 



In Maryland. — In March, 1894, the scale was sent to the Divis- 

 ion of Entomology on peach twigs from a large peach orchard in 

 Riverside, Charles Co., Md. It was learned that the scale had been 

 introduced in 1887 and 1888, on peach trees purchased of a New 

 Jersey nursery. Many of them had died, and nearly all of those 

 that remained were found to be thoroughly encrusted with the 

 scale, so that at the time of examination they were being taken up 

 and destroyed. (Other trees to which the scale had spread, had 

 been treated by their owner during the preceding winter, apparently 

 with good results, with the three principal winter washes, viz., 

 6trong kerosene emulsion ; lime, salt, and sulphur ; and resin wash.) 

 A trunk-washing in April with strong kerosene emulsion was suc- 

 cessful to the extent of killing 90 per cent of the scales. Several 

 sprayings were made during the summer with different mixtures, — 

 some of them under direction of Mr. Coquillett, — by which most of 

 the scales were killed. At the time of Mr. Howard's report (from 

 which most of these items relating to the eastern presence of the 

 scale have been drawn) in August, it was thought safe to say that 

 the insects would be completely stamped out in this locality by the 

 close of the year. 



In Florida. — At the same time of the discovery of the Maryland 

 locality, the scale was also received from De Funiak Springs, 

 Florida. At the request of the fruit-growers of that section of the 

 State, the Department of Agriculture sent Mr. H. G. Hubbard to 

 make examination and report. The. insect was practically confined 

 to the peach and plum, but occurred also, in small numbers on 

 Kieffer pears, and on pecan and persimmon. Many thousands of 

 trees were infested, and nearly every orchard within a radius of five 

 or six miles was more or less attacked. Arrangement was made for 

 the Experiment Station of Florida to undertake the work of destroy- 

 ing the scale, by going over all the infested trees in the district with 

 five or six applications of the resin wash. If the weather should 

 prove favorable for the use of the wash, there was reason to believe 

 " that the nuisance will have been abated by the close of the season 

 in Florida, although extermination [from the peculiar conditions of 

 the infested locality] may not be found possible,"
