and of the “bastard”? variety. The condition of the seedlings 
at the time of analysis is shown in FIGURE I. The outward 
appearance of the two kinds of seedlings was practically the 
same. Likewise, the differences among the figures in our table 
for general chemical composition are too slight to warrant any 
other conclusion than that the seedling metabolism was, in gen- 
eral, essentially the same in both varieties. The analyses were 
made 12 months after seeds were planted.

Analyses were made by the usual drying and incineration methods. The pot. 
tions Beenie to comparative analysis were approximately of the same morphological 
location _in each variety. The most significant differences seem to be the slightly 
larger proportion of water in the ‘‘red’’ wood and the relatively greater quantity 
solids, especially inorganic matter, in the ‘* bastard’’ samples
