Heatinff seed rooms to destroy insects, E. G. Montgomery {Jour. Anier. Soc. 

 Aaron 9 (Wn), No. 3, pp. 105-108, fig. i).-This paper describes a method for 

 hating seed rooms to destroy insects, as devised and used by the department 

 of farm crops at Cornell University. By using half-bushel grain receptacles 

 having perforate<l metal tops and bottoms a temperature of 120 F. can be at- 

 tained in a half bushel of gi-ain within 5 to 6 hours with a room temperature of 

 130° The treatment was found sufficient to kill mice as well as insects in all 

 stages of development without any injury to the germinability of the gram. 



HORTICTJITURE. 



Saving vegetable seeds for the home and market garden, W. W. Tracy, sb. 

 (U S Dept Agr., Farmers' Bui. 884 (1917), PP- 16. figs. 5).-This publication 

 gives directions for saving the seed of our garden vegetables. The subject 

 matter is discussed under the general headings of present shortage of vege- 

 table seeds how the supply may be increased, plants which bear seed the year 

 they are planted (annuals), plants which require a winter rest before producing 

 seed (biennials), and labeling, fumigating, and storing vegetable seeds. 



Control of diseases and insect enemies of the home vegetable garden, W. A. 

 Oeton and F. H. Chittkndkn {U. S. Dept. Agr., Farmers' Bui. 856 {1911), pp. 

 70 figs. S2).— This publication discusses plant diseases and insects, prevention 

 of' diseases and insect infestation, formulas for fungicides and insecticides, 

 mechanical methods of control, spraying methods, general crop pests and dis- 

 eases, and the principal garden crops and the insects and diseases that attack 



them. 



[Experiments with vegetables] {Pennsylvania Sta. Bui. Utl {1911), pp. 31- 

 34, figs. 3).— A brief statement of progress made in investigations with cab- 

 bage, tomatoes, and asparagus, essentially the same as that noted in the pre- 

 vious report (E. S. R., 38 p. 40). 



Home storage of vegetables, J. H. Beattie {V. S. Dept. Agr., Farmers' Bui. 

 819 {1911), pp. 22, figs. 20).— A popular treatise including directions for con- 

 structing storeruoms and outdoor storage cellars, together with specific In- 

 formation for storing different kinds of vegetables and also apples. 



First generation crosses in cucumbers, H. K. Hayes and D. F. Jones {Con- 

 necticut State Sta. Rpt. 1916, pt. 5, pp. 319-322, pi. 1).—An experiment to test 

 the value of first generation crosses of cucumbers was started in 1912 when the 

 following crosses were made: Early Russian X White Spine, White Spine X 

 London Long Green, London Long Green XFordhook Famous, and Fordhook 

 Famous X White Spine. In view of the prevalence of mosaic disease in 1914 

 and in 191.5, only the preliminary results secured in 1913 are given here. 



The results for one .season indicate that first generation cucumber crosses may 

 frequently be expected to exceed the higher yielding parent in yield. The only 

 cross that did not exceed the average of the parents in any character by an 

 appreciable amount was the London Long Green XFordhook Famous cross. The 

 parents of this cross produced the same type of vine and same size of fruit, 

 whereas the other three crosses were between parents differing in vine habit 

 and in size of fruit. 



Melon growing in Indiana, H. J. Reed {Indiana Sta. Circ. 68 {1911), pp. 16, 

 figs. i4).— This circular discusses the present status of the cantaloup and 

 watermelon business in Indiana, and gives suggestons relative to their culture, 

 harvesting and marketing, varieties, and the control of insects and diseases. 



The effects of cross- and self-fertilization in tomatoes, H. K. Hayes and 

 D. F. Jones {Connecticut State Sta. Rpt. 1916, pt. 5, pp. 305-318, pis. 2).— The
