Results 
Approximately 16,000 coniferous seedlings and transplants of 
all species were set out in all the plots. Of these there was 
found growing in October, 1921, a total of 743 or about 4.6%. 
Of the 70 species of trees, both conifers and hardwoods, which 
were tried in the seedpots only 173 individual seedlings wxre 
ahve in October 1921. These striking figures, however, should 
not be taken at their apparent value, for this is greatly discounted 
by numerous factors. Many of the species tried were palpably 
unsuited to the sites ; a considerable number of plants were 
poorly planted ; rodents and livestock destroyed entire groups ; 
severe and untimely droughts took heavy toll of tender seed- 
lings ; unskilled labor and lack of trained supervision were res- 
ponsible for still more loss, etc. etc. 
Below are presented the record of conditions in October 1921 
in each of the eight experimental plots.
