470 JOURNAL OF FORESTRY 



Some of the ground is agricultural, other parts topographically unfit 

 for such use. Abandoned fields with an area of 213 acres have been 

 planted. Since this area lies in 79 tracts, the planting can only be for 

 demonstration purposes. There are, however, some tracts as large 

 as 8 to 10, and one of 28 acres. A description of each of these sample 

 plantings forms the principal part of the report. The planting is, of 

 course, almost entireh^ of hardwoods. 



Pruning and thinning, or rather improvement felling experiments, 

 and some in natural regeneration, have also been carried on. We 

 have not noticed in the accounts anything of a striking .nature, except 

 that an attempt to reforest the largest area by nuts of Black walnut, 

 hickory, and oak proved a failure, apparently because coppice shoots 

 were interfering. On another plot some of the walnuts, grown from 

 nuts, when 6 years old, so far as not straight were coppiced, and the 

 coppicing was repeated. It is not quite clear what the object of the 

 experiment is, unless to secure the more rapid growth of the coppice 

 shoots, which, however, is not persistent. It seems also that coppice 

 shoots are less liable to "fork." 



In a "woodlot demonstration" in another part of the State, which 

 we would have expected to have to do with an existing woodlot, this 

 resolves itself also into a plantation of 1^ acres, on which a number of 

 non-indigenous trees are used, notably some conifers. 



An account of prize essays and of a forestry exhibit is followed by a 

 number of educational articles, among which one by the well-known 

 dendrologist. Prof. Stanley Coulter, on fifty-four of the tree species of 

 Indiana, including some introduced ones in the reservation. The re- 

 port is well illustrated and printed on good paper, worthy of a State 

 docimient. B. E. F. 



Canadian Woods for Structural Timbers. Bulletin 59, Dominion 

 Forestry Branch. Prepared at the Forest Products Laboratories of 

 Canada by H. N. Lee under the direction of J. S. Bates. Ottawa, 

 Canada. 1917. Pp. 44. 



This bulletin is composite in character, evidently with a view to 

 inform the general wood user. It opens with a brief statement of the 

 timber supply of each province and the character of the forest. This 

 is followed by a short description of the general properties of wood, 

 largely as related to the mechanical qualities. 



The bulk of the text is given up to a discussion of the most important 

 coniferous woods of Canada, mainly from the standpoint of their
