842 EXPERIMENT STATION EECORD. 



Experiment to determine the most suitable distance apart for planting in 

 nurseries, G. D. Hope and H. R, Coopek (Indian Tea Assoc, Sci. Dept. Quart. 

 Jour., No. 2 (1915), pp. 36-^8). — The results of this experiment, which was 

 conducted at the Tocklai Experimental Station, indicate that the width of 

 planting tea seed best suited for nurseries is not less than 9 in. and not more 

 than 12 in. Between these limits the choice would be dependent on the kind 

 of seed and soil. 



Suggestions for the manurial treatment of tea soils, G. D. Hope and P. H. 

 Caepenter (Indian Tea Assoc. [Pamphlet], 1915, pp. II-\-88, pi. 1). — A discus- 

 sion of the principles and practice of manuring tea, including a classification of 

 the tea soils of Northeast India with special reference to their manurial 

 treatment. 



Experiment to determine the effect of lime on the growth of tea seedlings, 

 G. D. Hope and H. R. Cooper (Indian Tea Assoc., Sci. Dept. Quart. Jour., No. 2 

 (1915), pp. 39, 40). — In this experiment, which was conducted at the Tocklai 

 Experimental Station, the soil was known to require lime. Both the check 

 plat and limed plat were given cattle manure at the rate of 20 tons per acre, 

 the limed plats receiving slaked lime containing 51 per cent calcium oxid at the 

 rate of 1 ton per acre. As compared with the check plat there was a 49 per 

 cent increase in weight of 100 plants, a 28 per cent increase in average height, 

 and a 9 per cent increase in average circumference of the tea seedlings on the 

 limed plat. 



* A summary of the investigations of Dr. P. van Romburgh, C. E. J. 

 Lohmann, and Dr. A. W. Nanninga (1892-1906), J. J. B. Deuss (Dept. 

 Landb., Nijv. en Handel [Dutch East Indies'], Meded. Proefstat. Thee, No. 31 

 (1914), pp. 58). — The investigations here summarized consist largely of chemical 

 studies of the volatile products of fresh fermented tea, the content in caffein 

 and other alkaloids in different cultivated teas, fermentation and fertilization 

 studies, investigations of changes taking place in the tea leaf, manufacturing 

 tests, etc. 



Medicinal plants and their cultivation in Canada, J. Adams (Canada Expt. 

 Farms Bui. 23, 2. ser. (1915), pp. 60, figs. 36).— This bulletin deals with the 

 medicinal properties of certain plants and discusses the possibility of growing 

 these plants in certain parts of Canada. Consideration is given to soil, climate, 

 and cultivation ; collection and drying ; imports and exports of medicinal plants ; 

 medicinal plants for which there is a considerable demand; medicinal plants 

 used in moderate or small quantities ; and foreign medicinal plants which might 

 grow in Canada. 



A bibliogi"aphy dealing with the various medicinal plants is included. An 

 appendix contains a note with reference to changes in medicinal plants made in 

 the 1914 edition of the British Pharmacopoeia. 



Eield book of western wild flowers, Margaret Armstrong (Nero York and 

 London: C. P. Putnam's Sons, 1915, pp. XX-]-596, pis. 48, figs. 500).— A popular 

 field book illustrating and describing a large number of the commoner wild 

 flowers growing in Washington, Oregon, California, Idaho, Nevada, Utah, and 

 Arizona. The flowers found only in the Rocky Mountains are not included. 

 Attention is called to the fact that exceedingly few of the western flowers cross 

 the Rockies and are found in the East. 



New Zealand plants suitable for North American gardens, L. Cockayne 

 (Wellington: Govt., 1914, pp. 35). — A descriptive list is given of evergreen and 

 deciduous trees and shrubs, climbing plants, herbaceous and semiwoody plants, 

 and ferns believed to be suitable for open air culture in the Pacific coast region, 

 where there is little danger of severe frosts.
