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 1 2 months after seeds were planted.

* Analyses were made by the usual drying and incineration methods. The por- 

 tions subjected 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 of 

 solids, especially inorganic matter, in the "bastard" samples.
