 the washing of the seed into suitable interstices of the grass cover. 



Where naked soil is to be reforested, the use of plants with ball 

 taken from the grass sowings is recommended as sure and cheap.

MENSURATION, FINANCE, AND MANAGEMENT 



Osmaston, of the Indian Forest Service, re- 

 Bainboo ports a series of very careful and detailed meas- 



Incrcment urements of the rate in height growth of bamboo 



on 17 specimens, measuring at six in the morning 

 and six in the evening. The young culms appeared early in August 

 and height growth was completed by end of November. Growth at 

 first was very slow, rising gradually for 4 to 6 weeks until about 12 

 feet high, when the maximum rate was attained (relative humidity then 

 being greatest) and maintained for several weeks, then gradually declin- 

 ing until growth ceased in November. It was found that the culms 

 started, contrary to other observers, toward the middle of the rainy 

 season and grew until two months or so after that season ended. The 

 growth at night was mostly found near double that of the daytime. 

 Thirteen inches in 24 hours was the most rapid growth ; this culm 

 reached full height (71 feet) in y/2 months. The total daily growth 

 of one specimen measured from day to day was as follows : 40. 34, 

 52, 56, 78, 48, 72, 82, 78, 92, 64, 102, 108 hundredths of an inch — about 

 9 feet in 9 days.

W. H. Kenety, of the Forest Experiment Sta- 



W'hiic Spruce tion at Cloquet. Minn., publishes an interesting 



in report on his findings regarding the growth of 



Minnesota white spruce, and urges its u.se as an investment 



for pulp and paper companies for the following 



reasons : 



"What investment," he asks, "would be necessary to establish a plan- 

 tation large enough to supply a mill using 25,000 cords of pulpwood 

 annually, the first cut, other than thinnings, to be made in 50 years? 



"The data collected show that 50 cords per acre is a probable vield 

 at the end of 50 years on the proper type of soil. The cut from 500
