Trip of Juxe 4 to Stamford, Conn. 



Seven members and guests were present on this, the Club's first 

 scheduled trip to the Bartlett Tree Research Laboratories. The 

 trip was made possible through the kindness and hospitality of Dr. 

 Stanley W. Bromley, assistant entomologist on the laboratories' 

 stafif. Doctor Bromley explained the history and purposes of the 

 laboratories and personally conducted us through the study labo- 

 ratories and grounds, arboretum and gardens, explaining the land- 

 scape planting experiments, fertilizer investigations, investigations 

 on blight-resistant chestnuts, insect and disease control tests, tree 

 working equipment, tree-shaping and pruning experiments, etc. 

 The characteristics of scores of injurious insects were explained, 

 and their life histories and the marks of their work on host plants. 

 The grounds comprise 200 acres and contain over 800 different 

 species and varieties of trees and shrubs, including a wonderful 

 collection of nut-trees — walnuts, hazelnuts, filberts, pecans, etc. 

 Among the interesting trees and shrubs studied were the tree alder 

 (Alnus hirsuta var. sibirica), angelica-tree (Aralia japonica). blue 

 ash {Fraxinus quadrangulafa ), flowering ash (F. ornus), J\Ian- 

 churian ash (F. inandshnrica), two other very rarely seen exotic 

 ashes (F. griffithi and F. holotricha), Japanese birch (Betula 

 japonica var. mandshurica), blue Atlas cedar (Cedrus atlantica 

 var. glauca ) . Chinese corktree (Phellodcndroii chinense). Chinese
