          34793. POPULUS DELTOIDES.
Cottonwood. From A. Woeikoff, Novospaska, 
Russia. As cottonwoods are
such valuable trees on the Great
Plains, and so variable, it is thought
worth while to test this form from
Simbirsk Province, Russia, in comparison 
with the American forms. It
may have more vigor or show other
characteristics of value in the northwest.

22861. POPULUS LAURIFOLIA. 
From Frank N. Meyer, Wutaishan, 
China. White-barked poplar,
growing at high altitudes and valuable 
for sand bindinge Frequently
planted along ravines to prevent
erosion and damage to lands below.
Suggested for similar use and avenue
planting in this country. The young
bark of the tree is green.

30147. POPULUS NIGRA.
Lombardy poplar. Through Mr. Frank
N. Meyer, from Bas-lengar, Chinese
Turkestan, called "Tagh Terek."
Grows to be very large and is singularly 
free from galls or diseases;
especially well adapted to semi-arid
conditions, and desert regions under
irrigation. May prove unusually
hardy.
