belter in richer ground and especially in ground where potash predominates. 

 The usual practice in sowing it around here is to irrigate the grain stubble 

 field if there h;is not been rain enough, to sow nearly a bushel of seed to an acre 

 right on the stubble and just cover the seeds with the old native plow, and then 

 drag a pole over the field to smooth it somewhat , which of course helps the 

 seeds to come up more evenly and also decreases the surface evaporation. It 

 is sown broadcast. It likes the ground well drained, either naturally or arti- 

 ficially, and the earlier it is sown the better it is, within the time mentioned." 



28369. Bambos arundinacea Retz. Bamboo. 



From Sibpur, Calcutta, India. Purchased from Maj. A. T. Gage, superintendent, 

 Royal Botanic Garden. Received July 16, 1910. 



"This bamboo does not spread rapidly and it is seldom necessary to keep the plant 

 in check. It never becomes a troublesome weed, and it can be extirpated without 

 difficulty, if desired. " {Gage.) 



See No. 21317 for further description. 



28370. Picea breweriana S. Watson. Veiled spruce. 



From near Kerbyville, which is reached by stage from Grants Pass, Oreg. Col- 

 lected by Mrs. A. J. Adams; purchased from. Miss Alice Eastwood, Gray Her- 

 barium, Harvard University, Cambridge, Mass. Received July, 1910. 



"This is one of the rarest and most unique of all the spruces. It grows only on the 

 summit of the Siskiyou Mountains of northern California and southern Oregon. I 

 saw some small trees on Canyon Creek in Trinity County and I should call the tree the 

 veiled spruce rather than the weeping spruce. It grows to quite a height, 70 or 80 

 feet, and with a diameter of 1 to 2 feet. The drooping branches are clothed with long 

 pendent, slender branchlets. The tree is delicate and graceful in outline, but not 

 funereal or sad. The cones resemble those of the Norway spruce. " (Eastwood.) 



Distribution. — Dry mountain ridges and peaks near the timber line on both slopes of 

 the Siskiyou Mountains on the boundary between California and Oregon at an eleva- 

 tion of 7,000 feet, and on the Oregon coast ranges at the headwaters of the Illinois 

 River, at an elevation of 4,000 to 5,000 feet.
