can cow be seen, no other trees on the grounds have been infested, 

 but it is a little early to feel absolutely sure on this point. 



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 my assistant, Mr. Lounsbury, to 

 different nurseries to look for them. He reported that on April 

 19 he found the San Jos^ scale on two plum trees, two pear trees 

 and a rose bush in Eosliudale, 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 in West Roxbury, who 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 Jos^ 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 bought from the Cambridge nur- 

 series, where they had been growing three or four j^ears. The 

 Cambridge nursery was then visited, and pear, peach and apple 

 trees were found infested with the scale, and many of the worst- 

 infested trees were dead. As no stock had been added to this 

 nursery for three years, these trees must have been infested at 

 least that length of time. I have not been able to learn from 

 what source the stock in this Cambridge nursery was obtained. 



On July 9 I received a twig of an apple tree from Mr. W. W. 

 Rawson, with the request to inform him what the matter was with 

 it. An examination showed that it was infested with the San 

 Jose scale. Further correspondence revealed the fact that the 

 twig came from an apple tree in the orchard of Mr. E. E. Cole, 

 in the town of Scituate. Mr. Cole wrote me that the orchard 

 contained ninety trees that were set out three years ago. It is 

 situated in a protected spot with trees on three sides, and is within 

 two miles of the ocean in a direct line. He also wrote me that 

 the trees were received from Mr. Rawson, who informed me that 

 he obtained most of his nursery stock of that description from 

 the Shady Hill Nursery Company. 



It is therefore probable that the Shady Hill nurseries received 

 infested stock from some outside nursery, possibly in New Jersey, 

 and have unintentional!}' become a centre of infection for orchards 

 in the eastern part of this .State. To what extent this pest has 

 become distributed through the State it is impossible to say, but
