Table 1 gives the record of trees which were planted, those which died ami those which survived on the two soils. About 30 percent of the trees survived on Merrimac loamy sand and 56 percent on Charl- ton line sandy loam. Norway spruce and river birch showed notice- ably better survival on Charlton line, sandy loam than on Merrimac loamy sand. Conifers and hardwoods both showed better survival on Charlton soil. Black birch was a total failure on both areas. The Charlton soil was more favorable lor the growth of conifers in gen- eral, ami the Merrimac soil for that of hardwoods. Selection of Trees to be Studied A Her the preliminary examination it was concluded that, no les^ than eighl and preferably ten trees of each species should he studied in order to give a good representation. Later on it became evident- that the amount of work involved in conducting the held excavation and charting of roots would not. permii the investigation of more
