the time the seed was wanted (early fall) many of the seed crops 

 had not been collected. Likewise it took time to determine 

 whether there would be any crops at all in the case of some 

 species. This resulted in delay in getting the work started. By 

 the middle of January eighteen species had been obtained from 

 commercial seedmen and of these only seven produced results that 

 were in any way satisfactory. On the other hand, through the 

 kindness of various members of the Forest Service throughout 

 the United States, twenty-six species were secured and practically 

 all of these produced good results. Due to these facts anyone 

 undertaking experiments of this kind in the future must look a 

 long ways ahead for a good seed supply. The following series of 

 tables gives the source of the seed obtained together with what 

 information was available as to date and place of collection. The 

 nomenclature used here and throughout this report is that used 

 by the Forest Service and is according to Forest Service Bulletin 

 No. 17 by G. B. Sudworth.
