Murrill: Field Meeting of Pathologists 309 



sery, and the seed farms of Orange, Milford, and Woodmont. 

 At the nursery, Mr. Coe exhibited many dwarf trees he had 

 brought from Japan, as well as an interesting climbing Hy- 

 drangea, excellent for walls, and the original plants and parents 

 of the hybrid box privet, a border shrub of great promise. An 

 hour's stop was made at Savin Rock for dinner, and then the 

 party proceeded to the Assembly Hall of the Experiment Station 

 for the evening meeting. 



Dr. Hartley, Director of the Rhode Island Experiment Station, 

 presided at this meeting, the general subject of which was "Tree 

 Diseases." Dr. A. H. Graves spoke on ''Resistant Chestnut 

 Trees " ; Dr. Florence McCormick on White Pine Blister Rust " ; 

 Professor Butler and Mr. Stoddard on Spraying Trees " ; and 

 Dr. Clinton on Peach Yellows." Most of these talks were illus- 

 trated with lantern slides and some with microscopic mounts. It 

 seems to be established that blister rust infects pine needles 

 through their breathing-pores ; and that peach yellows, probably 

 an enzymatic disease, may be transmitted from one tree to an- 

 other by grafting with bud or bark. 



An early start was made Wednesday morning for Storrs, where 

 the Agricultural College and Extension Bureau are located. The 

 first stop was at the Barnes Brothers' apple, pear, and peach 

 orchards, to see a commercial plantation of dwarf Mcintosh 

 apples ; a dusting machine in operation throwing clouds of dry 

 sulphur in the air ; and a peach orchard that had been entirely re- 

 newed and probably saved from yellows by proper treatment with 

 sodium nitrate and other fertilizers. 



The largest greenhouses in America are located at Cromwell. 

 About 22 acres are under glass, one house being 800 feet long by 

 82 feet in width and another 500 by 480 feet, the latter entirely 

 filled with roses. Ferns, begonias, palms, carnations, chrysan- 

 themums, etc., are also grown in abundance and under the very 

 best conditions. The establishment was far too large to admit of 

 a thorough examination, so we ins^pected a few of the larger 

 houses, the storage rooms, and the packing rooms, and then con- 

 tinued our journey toward Hartford. 



At Wethersfield, we grouped ourselves beneath the largest elm
