Easter Lily Bulbs, Production of, in U.S.A. By Geo. W. Oliver 

 (U.S.A. Dep. Agr., Bull. 120; illustrated).— The bulbs for flowering at 

 Easter have hitherto been largely imported from Bermuda and Japan, but 

 are not satisfactory from these sources owing to the limited area of arable 

 land, and consequent absence of crop rotation, which causes weakness and 

 deterioration in the bulbs, resulting in almost certain fungoid disease, 

 which is perpetuated in reproduction by the usual vegetative methods. 



It has been found that seedlings, especially the second generation, are 

 practically free from disease, and produce flowers even quicker than by the 

 old method. 



The pamphlet shows that bulbs can be readily and profitably raised 

 for commercial cultivation in the States, and that disease-resisting strains 

 can be easily maintained. — C. H. L. 



Education, Horticultural. By C P. Close (U.S.A., Peninsula 

 Hort. Soc. Trans., 190S, p. 94). — A lecture dealing with the means of 

 diffusing horticultural information in Maryland, U.S.A., under the 

 headings : Industrial and Agricultural High Schools, Farmers' Institutes, 

 Movable Railroad-Coach Schools, Movable School of Horticulture, Fruit- 

 growers' Organisations, Parlour Lectures to Fashionable Audiences, 

 Country Club Horticultural Education, Popular Lectures. — F. J. C. 



Electricity, Influence of, on Vegetation (Bev. Hort. June l, 

 1908, pp. 248-9). — An interesting report of a lecture given by M.» 

 Magnenne to the Societe Nationale d' Agriculture, supplemented by data 

 given by M. Gaston Bonnier. — C. T. D. 



Erythroniums. By W. I. (Gard. Ghron. No. 1110, p. 212, figs. 94 

 to 96 ; April 4, 1908). — " Dog's-tooth violets are easily cultivated and are 

 quite hardy in this country when given the requisite conditions." Then 

 follow some remarks as to what the conditions are, and descriptions are 

 given of the six best species for garden cultivation. Three species are 

 figured. — G. S. S. 



Eucalypts. By Gifford Perichot (U.S.A. Dept. Agr., Forest Service, 

 Circ. 59, October 1907).— Deals with the gum trees, particularly 

 Eucalyptus globulus, and contains much useful information about its 

 range, habit and growth, planting and the economic uses of the timber as 

 produced in California. In America, however, the blue gum tree must be 

 regarded as only suited for the valleys and canons, as it cannot withstand 

 cold cutting winds or exposed situations. The chapter on cost of 

 planting and returns is highly interesting. — A. D. TI . 



Forcing- Flowering-Shrubs, A Method of. By Professor Molisch 

 (Garten- Zeitung, May 1908).— This article points out that flowering-shrubs 

 which have been immersed in warm water for periods of from ten to 

 sixteen hours can then by ordinary methods be brought into flower a week 

 or ten days earlier than plants which have not been treated in this manner. 

 The effect of the immersion is purely local, so that if half a plant only 

 be immersed that half will be in flower when the buds on the remainder 

 are still dormant.
