This followed closely the work on 

 the American white ash with its "back- 

 bone filling." The blocks referred to 

 are from four to six inches long and 

 between them rubber roofing paper was 

 placed to separate the sections. It is 

 said that the durability of the paper 

 does not count particularly, although it 

 will last for a number of years, because 

 its work was accomplished in the sepa- 

 ration of the segments as they were put 

 in — water cannot get in the cracks. 



PEST ON PLUMS. 



The plum web-spinning sawfly is dis- 

 tributed generally over South Dakota, 

 but it is the eastern half of the state 

 that suffers most severely from the rav- 

 ages of the larva" of this pest. The 

 larvffi are gregarious and live and feed 

 in webs which they spin about the leaves 

 and twigs of their food plants. The 

 foliage of plum trees and sandcherry 

 bushes constitutes the preferred food 

 of the pest and such trees and bushes 

 may be entirely defoliated during June 

 and July.

 early June. After mating, each female 

 lays forty-six eggs on an average and
