II HATCH EXPERIMENT STATION. [Jan. 



the horticultural department of the Massachusetts Agricult- 

 ural College, which proved to be the dreaded San Jose scale. 

 These trees, according to the record books, came from the 

 J. T. Lovett Company, Little Silver, N. J., in the spring 



of 1894. 



Wishing to determine whether any of these insects had 

 survived the winter, I had two of the trees taken up and set 

 out in the cold part of the insectary greenhouse, and the 

 remaining infested trees were burned. Scales appeared on 

 the growth of the previous year, so that the insects suc- 

 ceeded well at least during the summer of 1894. On June 

 10, live scales were observed on the trees transplanted to 

 the insectary greenhouse, and on the 14th the young were 

 swarming all over them, and even extended to some small 

 apple trees growing near in the same part of the greenhouse. 

 As this seemed to settle the question of their ability to sur- 

 vive our winters here in Amherst, or at least the winter of 

 1894-95, which was an average one, I had all these trees 

 very carefully burned, to prevent any further spreading of 

 the pest. As soon as it was discovered that the San Jose" 

 scale had been received here on nursery stock from outside 

 of the State, I feared that other nurseries might have become 

 infested in a similar manner, and therefore I sent Mr. Louns- 

 bury, who was my assistant at that time, to different nurs- 

 eries to look for them. He reported that on April 19 he 

 found the San Jose scale on two plum trees, two pear trees 

 and a rose hush in Roslindale, Mass. The plum trees were 

 badly infested with living scales, while the pear trees and 

 rose bush were but slightly so. The scales occurred on all 

 parts of the trees, but were the least numerous on the new 

 growth. The pear trees had been on the grounds for three 

 years and the plum trees two years. Mr. Lounsbury was 

 informed that these trees were obtained from a local agent 

 at West Roxbury, \\ ho claimed to have purchased them from 

 the Shady Hill nursery, Bedford, Mass. On April 23 Mr. 

 Lounsbury visited the Shady Hill nursery, and found the San 

 .lost' scale alive in large numbers on several different varieties 

 of apple trees. Mr. Kohler, in charge of the nursery, told 

 him that these trees were brought from the Cambridge nurs- 

 eries, where they had been growing^ three or four years.
