446 EXPERIMENT STATION RECORD. 



it was noticed that a living moss cover appeared to decrease the growth accre- 

 tion somewhat. Experiments made during the past 3 years and here presented 

 indicate that a living moss cover does retard the growth of young trees con- 

 siderably during a dry season, although growth may be somewhat stimulated 

 during a wet season. In a dry season the moss appears to take up most of the 

 rain and allows very little to pass through, as was noted in connection with 

 natural regeneration (E. S. R., 20, p. 945). In a wet season it is possible that 

 the moss cover may aid in storing moisture for use during the dry periods. 

 These results are to be further studied. In general it appears advisable to 

 remove the litter from the forests about every third year to prevent a heavy 

 growth of moss. 



Determination of quality of locality by fiber length of wood, C. D. Mell 

 {Forestry Quart., S {1910), No. 4, pi). Jil9-422). — Some preliminary micro- 

 scopical studies of wood fiber of Juglans californica, collected from trees grow- 

 ing in different soils and situations, indicate that the length of fiber is a func- 

 tion of site quality. 



How to cruise timber, J. W. Shaw {Portland, Oreg., 1910, pp. 6-'/, dgms. 6). — 

 This is offered as a complete field manual for experienced cruisers, loggers, 

 and foresters, claimants, or for anyone desiring to learn to estimate timber. 

 In addition to the diagrams and explanations of the standard methods of esti- 

 mating timber, it explains the details of making estimates, including pacing, 

 surveying, making out reports, etc., and also contains a synopsis of the 

 requirements for the general plan of surveying and the establishment of corners 

 in public laud surveys of the United States. 



A comparison of Maine and Blodgett log rules, I. G. Stetson {Forestry 

 Quart., 8 (1910), No. //, pp. 427~432). — Some tables based on measurements of 

 actually cut trees are given whereby an estimate by either of the rules of a 

 stand of timber may be converted to an estimate of what the timber when cut 

 will scale under the other rule. 



Annual progress report upon state forest administration in South Aus- 

 tralia for the year 1909-10, W. Gill {Ann. Rpt. State Forest Admin. So. 

 Aust., 1909-10, pp. 12, pis. 7). — A statistical report of the year's planting and 

 other forest operations, revenues, and expenditures, together with a compara- 

 tive statement of the revenue, expenditure, and legislative provision for the 

 past 32 years. 



[Report of chief of forestry division], K. A. Carlson {Dept. Agr. Orange 

 River Colony, Ann. Rpt., 5 {1908-9), pp. 101-142).— In addition to a general re- 

 view of the work and a financial statement for the year ended June 30, 1909, 

 some condensed notes and directions are given for starting and caring for young 

 evergreen plantations, together with suggestions on the correct sowing of 

 wattles and robinia, iuul a number of lists of species recommended for different 

 conditions of soil and climate, rapid growth, timber, fuel, windbreaks, and hedges. 



The development of forestry in Ohio, J. W. O'Byrne {Ohio Forester, 2 

 (1910), No. 3, pp. 3-16). — A paper on this subject, discussed under the general 

 headings of early conditions in Ohio, early development and present possibilities, 

 the work of individuals and organizations, and present conditions and plans for 

 the future of Ohio forestry. A list of the more important literature pertaining 

 to Ohio forestry is appended. 



Reforesting, C. R. Pettis {N. Y. Forest, Fish and Game Com. Bui. 2, pp. 25, 

 pis. 14). — A revision and enlargement of Instructions for Reforesting Land 

 (E. S. R., 21, p. 143). 



Results of experiments in tree planting on Sable Island, W. Saundeks 

 {Canada Expt. Farms Rpts. 1910, pp. 5.'i, 55). — A brief report on the experi- 

 ments in tree planting undertaken at Sable Island in 1901 (E. S. R., 14, p. 152).
