HORTICULTURE. 47 1 



Trees and shrubs tested in Manitoba and the Northwest Territories, W. 



Saunders (Canada Cent. E.ipt. Farm Bid. 47, pp. 50, ph. 6). — In this bulletin the 

 results are given of a large number of trials of trees and shrubs grown at the experi- 

 mental farms at Brandon, Manitoba, and at Indian Head in the Northwest Terri- 

 tories during the past 16 years. The matter contained is a summary of the data 

 which have appeared in the various reports from these stations. The object in com- 

 piling the bulletin has been to present in convenient and condensed form an account 

 of the hardiness and desirability of different trees and shrubs for ornamental pur- 

 poses about the home. While the testing has been done at these 2 farms in west- 

 ern Canada it is believed that the results are applicable in the East, since plants 

 hardy enough to endure the climate of the Northwest may be planted with assurance 

 of success in any of the eastern parts of Canada. 



Species of the following shrubs and trees have proved hardy in the Northwest: 

 Juneberry, barberry, birch, Siberian pea tree (Caragana), hackberry, virgin's bower, 

 dogwood, native hazelnut, cottoneaster, hawthorn, broom (Cytisus), Eheagnus, hop,

 lilac, elm, arrowwood (Viburnum), the grape ( Vitis vidpina), balsam, spruce, and 

 tamarack. 



Species of the following plants have proved partially hardy, that is, they may be 

 killed back to the ground, but spring up each season, or may be only partially 

 killed back: Alder, birthwort (Aristolochia), southernwood (Artemisia), bitter- 

 sweet, hydrangea, privet, moonseed, ironwood, Periploca, mock orange, roses, elder 

 (Sambucus), linden (Tilia), and pine.

Native ornamental plants of New Mexico, E. O. Wooton (New Mexico Sta. 

 Bui. 51, pp. 40, pis. 12). — The author makes a plea for the use of native plants for 

 shade and ornament about the homes in New Mexico, and gives descriptions of a 

 large number of coniferous and deciduous trees, shrubs, vines, and other plants 

 which may be used for these purposes, with directions for handling them. 



Third annual convention of the Chrysanthemum Society of America 

 (Amer. Florist, 23 (1904), No. 858, pp. 597, 598). — An account of the proceedings of 

 the society at its meeting held in Boston, November 3 to 5. Score cards for judging 

 commercial chrysanthemums and chrysanthemums for exhibition purposes were 

 adopted. For commercial purposes the weighting of the different points was as 

 follows: Color 20, form 15, fullness 10, stem 15, foliage 15, substance 15, size 10. For 

 exhibition blooms color, stem, and foliage were given 10 points each; fullness, form, 

 and depth 15 points each, and size 25 points. 



The book of the iris, R. I. Lynch (London and New York: John Lane, 1904, 

 pp. XII -\- 214, pis. 37). — This is the twenty-first number in the series of handbooks 

 of practical gardening, edited by H. Roberts. Part 1 gives a description of the struc- 

 ture of the flower and its natural history. Directions are given for the culture of the 

 various irises. Chapters are included on hybrids and hybridizing, diseases, and 

 insects. Part 2 is devoted to a classification and descriptions of the various species, 

 with cultural notes under each species. 



Injurious effects of manure, U. P. Hedrick (Amer. Florist, 23 (1904), No. 856, 

 p. 530). — The author calls attention to the injurious effects which sometimes follow 

 a heavy application of manure to flower beds, due to the fumes of ammonia arising
