426 EXPERIMENT STATION EECORD. 



Plantations of forest trees, W. Saxtnders {Canada E.rptl. Farms 

 Ept. It^Do, ])p. .",1 -:')', ^ ])l. 1). — Notes on the belts and cluia])s of forest 

 trees planted on the experimental farm, with a detailed account of the 

 planting and condition. They have made rapid growth and suffered 

 bnt slight mortality. Lists are given, showing the species of decid- 

 uous and evergreen trees plauted, with the dates of planting and 

 number of trees set out. 



Experiments in fall and spring transplanting, J. Craig {Canada 

 Exptl. Fanns 7v^>/. i.S'.'A7, jW- ^J--JJ-^)- — Thirty each of 3-year-old trees, 

 from 8 to 10 ft. high, of green ash, black walnut, red oak, and Euro- 

 pean mountain ash were transplanted in the iall of 1892, 10 being 

 planted without pruning, 10 with three fourths of the last season's 

 growth removed, and 10 with the tops cut back to the main, stems. 

 In the following spring a duplicate collection was trausplanted and 

 treated in a manner similar to that set out in the fall. In the subse- 

 quent fall a comparison was made, and the fall-planted trees were found 

 to possess much more dead wood, sun scalds, and uneven growth than 

 those spring plauted. As a result, spring planting is advised iu most 

 cases. The details of* the experiment are shown in an accompanying 

 table. 



Pruning oaks in midsummer, J. Craig {Canada Exptl. Farms 

 Bpt. 1803, p. IV')). — A number of young oaks were cut back to 1, 2, 3, 

 and 1-year-old wood, respectively, with the result that those pruned to 

 the 3-year-old wood made vigorous, large growths, while all the others 

 were injured or killed. 



Ornamental trees and shrubs, W. Saunders {Canada ExptJ. 

 Farms Bpt. 1893, pp. -IG-ol). — The ornamental planting on the Central 

 Experimental Farm consists of 35 closely or openly planted clumps 

 containing 1,789 trees and shrubs of 225 named species and varieties. 

 A list is given showing the botanical and common names, and the 

 hardiness of the plants. In the arboretum oyer GOO species and varie- 

 ties are arranged in botanical groups. 



Propagation of ornamental shrubs and conifers, J. Craig ( Can- 

 ada Exptl. Farms Bpt. 18U3, pp. 115-117). — Various shrubs and coni- 

 fers were grown from cuttings which were made both from the ripened 

 and from the green wood. There seemed to be little difference in the 

 results. 



Trees and shrubs, S. A. Bedford {Canada Exptl. Farms Rpt. 1893, 

 pp. 3G;J-2(>7, figs. 2). — A report on the trees and shrubs set out in nursery 

 rows and shelter belts, the rate of growth, condition, species, and varie- 

 ties j)lanted; number of trees distributed, and tabulated notes on 

 experiments with trees as wind breaks. The Russian jioplar {Populus 

 hercolensis) and tSalix acntifoUa are proving most promising for wind- 

 breaks. The ash-leaf maple is forming good hedges. 



Trees and shrubs, A. MacKay {Canada Exptl. Farms Rpt. 1893, pp. 

 303-305, fi(j. 1). — Notes on the trees and shrubs grown on the North-
