" When only the fruit buds are killed, the wood being uninjured and the trees 

 in good condition, prune severely, cutting back the annual growth to two or 

 three buds. It may be expedient to cut some branches back even into two or 

 three year old wood." 



Horticultural -work {Oklahoma f^ta. Rpt. 1906, pp. SG-JfS). — Notes are given 

 on storing sweet potatoes, small fruits (E. S. R., 17, p. 664), and planting trees 

 for posts, wood, etc. 



The fundamental conditions for success in storing sweet potatoes are stated 

 to be potatoes healthy and free from bruises and cuts, dry when stored, and 

 kept dry while in storage, and the maintenance of temperature of the storage 

 room between 50 and 65° F. One method of storing the potatoes is to keep the 

 temperature of the storage room up to 00° for about a week as soon as the 

 potatoes are stored, giving good ventilation. Where this process is not con- 

 venient the tubers should be given all the ventilation possible, so they can dry 

 very rapidly for about 2 weeks. 



The book of market gardening, R. L. Castle {London and Neic York: John 

 tauG Co., 1906, pp. Ill, pU. 1^, figs. 6, dgms. 5). — This book discusses the busi- 

 ness aspects of market gardening, dealing with the selection of land, labor ques- 

 tions, crops, preparation of produce for sale, grading, packing, marketing, coop- 

 eration, taxes, crop returns, values, etc. This is volume 27 in the series of Hand- 

 books of Practical Gardening, edited by II. Roberts. 



Excessive feeding as a factor in producing variation in tomatoes, E. P. 

 Sandsten {Wisconsin .S7f/. Rpt. 1905, pp. 300-31 J/, figs. 11). — An account is given 

 of the variations obtained with the variety Spark's Earliana when the soil in 

 the greenhouse bed in which they were grown was fertilized with nitrate of 

 soda at the rate of 800 lbs., sulphate of potash 600 ll)s., and desiccated bone 

 1,000 lbs. per acre. 



The variations obtained by this excessive amount of fertilizers were as great 

 as those commonly observed in different varieties. Many of the modifications 

 in flower, foliage, and fruit are illustrated. Cuttings of the different plants, 

 when rooted and transplanted to the open field, reproduced the variations ob- 

 served in the greenhouse, and the writer is of the opinion that this method of 

 producing variation in plants by excessive feeding may play a very prominent 

 part in the securing of new varieties of plants. 



Rhubarb culture, Kunath {Arh. Deut. Landw. GeseU., 1906, No. 117, pp. 

 12-.'ilf. figs. .')). — An extensive account is given of rhubarb culture in Germany, 

 with analyses with reference to food and fertilizer constituents and suggestions 

 on the preparation of rhubarb for the table. Considerable data are given on the 

 yields secured in experiments with different varieties of rhubarb and on the 

 extent to which rhubarb is grown in different sections of Germany. 



Rhubarb culture in England, B. 'Skalweit {Arh. Deut. Landw. GeseU., 1906, 

 No. Ill, pp. Ji.5-51).- — An account of the commercial culture of rhubarb in Eng- 

 land, including directions for fertilizing rhubarb and a brief bibliography on the 

 subject. 



New fruit productions of the Department of Agriculture, H. J. Werber 

 {T\ iV. Dcpt. Agr. )'(<irhook 190.'). pp. 27.'>-2!i(i. pis. 7, fig. 1). — Descriptions are 

 given of a new citrange. 2 new limes, and 5 new pineapples originated under 

 the author's direction. 



The new citrange has been named Morton and is sweeter than either the 

 Rusk or Willlts, less bitter and almost seedless. It has resisted cold which has 

 greatly injured other oranges, and it is believed that it can be grown from 

 Tennessee and Arkansas southward and near the coast in Oregon and Wash- 

 ington. It will be chiefly useful as a breakfast fruit and for the preparation of 

 citrangeade. The two new limes have been called Pulmettu auU Lverglade.
