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 wére 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.
