ing of the character and quality of the underlying soil. This, in connection with a knowledge 

 of the requirements of the various species to be planted, will enable the forester to plant only 

 those species which will find the soil and situation congenial to their growth. In Scotland, 

 soils growing heather will generally be found most suitable for the growing of the Scotch pine. 

 When, however, there are mixtures with other plants, such as Polentilla tormentilla, Holcus 

 lanatus, several varieties of trees may succeed very well. The size of the plants will, more- 

 over, form a guide as to the fertility of the soil. Foxglove indicates a medium soil, inclined 

 to be dry, and a great variety of trees may be grown in soil on which it flourishes. The most 

 hopeless soil in its natural condition is that covered with species of Scirpus. Unless thor- 

 oughly drained, it is vain to expect any kind of tree to succeed on it. — C. R. Tillotson.

 anstalt. [Contribution from the Swedish State Forest Experiment Station.] Hafte 15. 288 

 p. Stockholm, 1918.] Jour. Forestry 17: 431-436. 1919. — Seven papers are included with the 

 administrative report, which deal with storm, insect and disease damage, tree-seed studies, 

 direct seeding, and mensuration studies. The investigative program for 1918-1920 includes 

 problems in forest regeneration, development of forest stands, studies in diseases and inju- 

 ries, exotic species for forest practice, and soil investigations. — E. N. Munns.

 local names for the plants; these species evidently differ from those appearing in most other 

 regions. — J. A. Larsen.

 Trans. Roy. Scottish Arboric. Soc. 33 : 40-43. 1919. — This is a letter from a forester addressed 

 to the owner of an estate, in which the forester goes into some detail concerning the planting 

 of both hardwoods and conifers on the estate, the yields and the returns from the plantations.

 — This article touches briefly upon the natural changes in forest successions which have taken 

 place in the past and are perhaps going on now, in their relation to the advisability of foresters 

 bringing about a change in the species of trees grown on a particular site when the old crop 

 is removed. Whether to replant with the same species or not depends on the health and vigor 

 of the cleared crop at its maturity, and the probability of the same species proving financially 

 the most promising for another rotation. — C. R. Tillotson.

965. Walkington, Alma. Plowing land before planting. Quart. Jour. Forest. 13: 133— 

 136. 1919. — Plowing wet, heavy land, while expensive, and later planting it to forest trees, 

 is preferable to pitting it in the fall and planting in the pits the following spring. Such pits 

 remain wet and unsuitable for the growing of trees. Plowed furrows, on the other hand, 

 have a. natural drainage down the field. In planting the plowed land, a dibble can be used, 

 this method being faster than digging a hole for each tree. The trees should not be set more 

 deeply than they stood in the nursery. — C. R. Tillotson.

 cular saw, particularly with large timbers. — C. R. Tillotson.
