860 EXPERIMENT STATION RECORD. 



larly in the Balkan region. A horticultural and industrial study was also made of 

 perfume roses and of the production of rose essence in Bulgaria. An account and 

 outline is given of this work. The manufacture of rose essence in Bulgaria is carried 

 on by the peasants in a crude manner, and it is believed that the industry can be 

 profitably extended in France and her colonies under more scientific methods. It is 

 proposed to undertake experimental work along this line. 



Different methods of making- rose cuttings, Yiviand-Mokel {Eev. Horl., 73 

 [1901), Xos. 15, pp. 357-360; 17, pp. 413, 414; 1^, PP- 435, 43^; 19, pp. 459, 460).— 

 The various methods of propagating roses by means of cuttings are described from a 

 practical standjxiint. 



The sweet pea and its failings {Amcr. Florht, 17 {1901), No. 691, pjp. 161, 162). — 

 The ojjinions of several prominent sweet-pea growers and seedsmen are given as to 

 the cause of the failures in recent years in growing sweet peas, especially in Massa- 

 chusetts. W. T. Hutchins is of the opinion that the failure is due largely to loss in 

 the vigor of the seed, and that before success can be obtained a new race of peas must 

 be bred up which will be more hardy and vigorous than those now in cultivation. 

 W. Atlee Burpee & Co. have tested the sweet-pea seed from France, England, Ger- 

 many, Oregon, California, and northern New York, and have l)een able to detect 

 aljsolutely no difference in the growth of vines from these seeds of widely different 

 origin, and are of the opinion that the trouble is due to some blight disease. Peter 

 Henderson & Co. have had sinnlar results with seed from different localities, and 

 attribute the failure to local conditions, complaints coming from some sections and 

 not from others. R. & J. Farquhar & Co., of Boston, are of the opinion that the 

 bliglit can be prevented by injecting bisulphate of carbon at the roots whenever the 

 first sign of the blight appears. The method of use suggested is to bore a few holes 

 around the roots of each plant, drop in the bisulphate, and cover up the hole again 

 so that the fumes i^ermeate all through the soil. 



Intensive horticulture in California, C. H. Shinx {Land of Sunshine, 14 {1901), 

 Nos. 2, pi>. 96-110, jih. 6, Jiij^. 6; 3, pp. 182-189, pi. 1, figs. 4; 4, pp- 276-289, ph. 6, 

 figs. 4)- — A biographical sketch of Luther Burbank, noting in some detail many of 

 the more imiiortant fruit, flower, and vegetal)le creations originated by him by 

 hybridization and selection; and of Carl Purdy, the California specialist on the cul- 

 ture and botany of Pacific Coast bulbs. This article is also reprinted as a separate. 



FORESTRY. 



A planter's notes on trees and shrubs, E. A. Popenoe {Induslrkdkt, 28 {1901), 

 No. 5, pp. 60-62 j.^^oU's are given on the behavior of trees and shrubs drawn from 

 nearly 20 years' experience in planting, chiefly on the trial grounds of the Kansas 

 Agricultural College and Experiment Station. Among the trees the tulip tree or 

 poplar is said to have proved fairly satisfactory, while other trees of the same family, 

 among them several magnolias, have been unable to withstand the climatic and other 

 conditions. Notes are given on the coral berry, moonseed, Akebia, and various bar- 

 berries, all of which are more or less adapted to the conditions existing in the region 

 covered by this report. 



The use of nitrate of soda in sylviculture {Bui. Soc. Vent. Forst. Belg., 8 {1901), 

 No. 3, pp. 144-149, figs. 8). — The use of nitrate of soda in seed beds for growing seed- 

 lings of a number of forest trees is strongly recommended. In the ca.se of black pine, 

 ash, maples, birch, hornbeam, and ailanthus, seedlings grown with and without 

 nitrate of soda were compared. Those receiving nitrate at the rate of 200 to 300 kg. 

 per hectare were decidedly in better condition of growth than those not receiving 

 the fertilizer. 



The succession of cuttings for deciduous high forests, Pilz {AJJg. Forst v.. 

 Jagd Ztg., 67 {1901), Oct., pp. 341-348).— iym-uf>ses the relative value of different 

 periods of cuttings upon the maximum production of oak and beech forests.
