with annual rainfall, a classification of ofTenses committed against the forestry laws and the 

 police court results, a list of nurseries, and statement of revenue, including a table showing 

 comparative revenue and expenditure; the total revenue amounts to only 12 per cent of the 

 expenditures. The supplement enumerates a list of 10 additions to the flora of Hong Kong and 

 adjacent territories. The report reveals the fact that this colony received almost 110 inches 

 of rainfall during the year, of which about 90 fell during June, July, August, and September. 

 Typhoon signals were hoisted twice during the year; considerable damage was done by these 

 storms. — Richard H. D. Boerker. 



1006. Anonymous. Report on the Botanical and Forestry Department (Hong Kong, China) 

 for the year of 1919. 17 p. [Received in the U. S. A. October, 1920.] — The report consists 

 of a collection of short notes dealing with the administration of this department and is 

 primarily of local interest. The notes deal with the activities in connection with the 

 botanical gardens and various grounds and nurseries in charge of the superintendent. The 

 forestry activities include the formation of pine (species not given) and broad-leaved {Eucalyptus 

 Tristania, and Casuarina) plantations, the care of such plantations, their protection from fire, 

 the work of the forest guards, the planting and care of roadside trees, miscellaneous planting, 

 the repair of roads and paths, the clearing of undergrowth for anti-malarial purposes, and the 

 granting of forestry licenses and permits. To the report are appended 6 tables dealing with 

 rainfall for the year, a classification of the offenses against the forestry laws and the police 

 court results of these, the expenditures on the nurseries, the revenue derived from all sources, 

 and the comparative revenue and expenditure for the entire year. The report discloses that 

 the annual rainfall was about 90 inches, or slightly above normal. Tj^phoon signals were 

 hoisted twice, the storms doing considerable damage. In 1919 the revenue amounted to 

 16 per cent of the expenditures, the highest revenue since 1913, Forestry licenses and timber 

 sales furnish the bulk of the income. The total number of persons proceeded against for 

 committing forestry offenses was 477; of this number 354 were convicted. — Richard H. D. 

 Boerker.

1011. Bruce, Donald. A white fir volume table. California Agric. Exp. Sta. Bull. 

 329. 41-Jf.5. 1921. — The author has prepared a 3-part volume table for the determination of 

 the average volume in board feet of trees of given diameters and heights. The "site" of any 

 given tract is determined by estimating the average height of the tallest tenth of the merchant- 

 able trees. If this be over 9| 16-foot logs, table 1 should be used; if 1\ or under, table 3; 

 and for intermediate values, table 2. The table is based on trees measured (or estimated) outside 

 the bark at 4^ feet from the ground, or on side-hill timber from average ground level. Trees 

 to 8 inches diameter inside bark in top were scaled in 16-foot logs with 0.3 foot trimming allow- 

 ance, by Scribner Decimal C rule. Table 1 was prepared after making 868 tree measurements, 

 table 2 after 303, and table 3 after 206 tree measurements. As the table is based on trees meas- 

 ured as if sound, unbroken, and completely utilizable, it is essential that percentage reductions 

 be made for rot, breakage, unused tops, and stumps. The cull percentage for white fir commonly 

 ranges from 15 to 35, due mostly to rot and breakage. — A . R. C. Haas.
