Grafting- tlie mango tree, H. K.'niGm: {Queensland Agr. Jour., 7 {1900), Nos. 1, 

 pp. 41, 43, ph. 2; 2, pp. 149-151). — The author states that this fruit can be easily and 

 successfully grafted at any time whether the sap is active or dormant. The first 

 three months of the growing season, however, when the sap is most active, is pre- 

 ferred. Pieces of bark without any portions of adhering wood are recommended for 

 use as grafts. Sections of the mango tree, it is said, will keep good for grafting pur- 

 poses from 3 to 6 months, depending upon the variety and constitutional vigor of 

 the specimen. Directions for grafting mangoes and illustrations of grafts are given. 



Pruning the magnolia, S. Mottet {Rev. Hort., 72 {1900) , No. 17, pp. 490, 491) . — 

 All the principal branches of Magnolia ahovata lenei were severely headed in before 

 the flowers opened in the spring. As a result scarcely any flowers were produced 

 that year, but the following spring an unusually abundant florification took place. 



FORESTRY. 



Forest trees and shrubs, A. Mack ay (Canada Expt. Farms Rjyts. 

 1899, 2^I>- o7'2-37(j). — A report is given on the forest trees and shrubs 

 under observation at the Northwest Territory Farm. Since 1896 

 investigations have been conducted on the cost of planting and culti- 

 vating forest trees. This test is closed with this report, as the trees 

 now cover the ground so that no further cultivation will be giv^en. It 

 was found that the cost of planting and cultivation of box elders set 

 at different distances from 2^ to 4 ft. varied from $6.55 to $7.60 per 

 half acre. For green ash set 2i ft. apart each way, the cost was 

 $7.61. When the seed was sown directly in the ground the cost was 

 somewhat greater than when the trees were started in a nursery and 

 afterwards t ransplanted. 



The arboretum is said to contain at the present time 371 species and 

 varieties of trees and shrubs, a considerable portion of which, it is 

 believed, will prove hardy in this climate. A list is given of 10 forest 

 trees suitable for the Northwest Territories. The species recommended 

 are box elder, American cottonwood. Balm of Gilead, American larch, 

 American elm, green ash, sharp-leaved willow, trembling-leaved pop- 

 lar, Riga pine, and Norway spruce. Each of these trees is described 

 briefly and its relative value for different purposes indicated. 



Importance of forest tree growing, D. C. Burson [Forester, 6 

 (1900), JVo. o',pj)- '^'^ 1 ''j8)' — P^xtracts are given of a paper read by the 

 author, in which some of the more important uses of timber are men- 

 tioned. The rapidity with which the forests are disappearing and the 

 vast extent of wood-working industries are said to attract immediate 

 attention to the financial side of forest tree growing. It is stated that
