THE PLUM:iSCALE. 



E here repeat an engraving showing the plum scale from page 311 

 vol. xvii. It was there called Lecanium cerasifex, but scientists 

 are not quite settled upon its exact name. This, it is observable, 

 is quite distinct from the San Jose scale, described on page 64. 

 Early in March we found some samples of this scale on a Glass 

 seedling plum tree, to our sorrow, for it means another destruc- 

 tive insect enemy. Near Burlington instances have been found 

 ■where it is very numerous indeed.
