From Turkestan. Received through Prof. N. E. Hansen, March, 1898. (4 pack- 

 ages.) 



"A native desert bush with linear leaves 3 inches long; attains a height of 15 feet; 

 much planted to hold the moving sands along the Transcaspian Railway, and esteemed 

 the best because the growth is quickest. Mr. Palettsky, the Government forestry 

 expert in charge of this work, showed me one-year plants in nursery 5 feet high and 

 well branched. This bush does well on sand and alkali deserts; the more it is cov- 

 ered with moving sand the better it grows, as the branches root quickly. Wood 

 heavier than water, good for fuel, but too brittle and hard to use in the arts."

" Used to bind the moving sand dunes along the Transcaspian Railway. A native, 

 large, bushy, fleshy, leafless tree, which grows slowly at first but attains a height 

 of 8 to 10 meters (24 to 30 feet). Grows well in the sand deserts and on alkali soils. 

 Wood makes excellent fuel, better than birch, heavier than water, but too brittle and 

 hard to use in the arts."
