The Apple Maggot (or Railroad Worm) does not appear to be spread- 

 ing. The only remedy lies in destroying all windfalls as soon as they drop, 

 so as to kill the contained maggots. Windfalls may be gathered each day

and either boiled and fed to stock, or buried in a pit and covered with lime 

 and over six inches of earth.' The maggots leave the fallen apples to 

 pupate in the ground. 



Experiments have been made to bury the pupae so deep by plowing 

 that the flies which emerge from the pupae would be unable to reach the 

 surface. It was found that the flies would find their way through five or 

 six inches of earth, so that there is probably little benefit from plowing. 



The Plum Curculio has not been so injurious in the localities known to 

 me as in some previous years, though plums and apples in some places suf- 

 fered severely. In controlling this beetle on apples and plums the chief 

 dependence should be on poison sprays. The regular spraying with poison- 

 ed Bordeaux, using lead arsenate in larger amount, combined with rigid 

 destruction of fallen fruit is the best practice. Jarring has some place in 

 protecting choice fruit on small apple trees and is valuable in protecting 

 plum trees. AVhen the beetles are numerous they can be removed from 

 small trees by jarring the trees in the early morning with a padded mallet 

 over a white cloth spread beneath the branches. The beetles which drop 

 should be gathered and burned or killed in coal oil. 



The practice recommended by some, of keeping a few plum trees as 

 fillers in the apple orchard to serve as traps for the curculio seems to me a 

 good one. The curculio has not, until the past season, injured the apples 

 of our College orchards, although they have bred each year in great num-
