Begulations under the Destructive Insect and Pest Act, with instructions 

 to Importers and exporters of trees, plants, and other nursery stock, C. 6. 

 Hewitt (Canada Dept. Agr., Ent. Branch Ore. 10 (1917), pp. 12).— This circu- 

 lar Is intended to guide persons importing plants and other nursery stock into

 and other nursery stock may be exported to the United taStes. 



Spraying for profit, H. E. Weed (Cleveland, Ohio: Hort. Puh. Co., 1917, 21. 

 ed., rev., pp. 64, figs. 37). — A practical handbook dealing with the control of 

 the more common injurious insects and fungus diseases (E. S. R., 11, p. 371). 

 The present edition has been revised and rewritten to include modem prac- 

 tice. 



Rules and regulations of the Secretary of Agriculture under the United 

 States Standard Container Act of August 31, 1916 (f7. S. Dept. Agr., Office 

 Sec. Circ. 76 (1917), pp. 8). — This circular contains the text of the act (E. S. 

 R., 35, p. 598) to fix standards for baskets and other containers for small fruits, 

 berries, and vegetables, and for other purposes, approved August 31, 1916, to- 

 gether with the rules and regulations governing the act in force and effective 

 on and after November 1, 1917. 



[Report of] department of horticulture, M. G. Kains (Pennsylvania Sta. 

 Rpt. 1915, pp. Ifffi, 468, pis. 2). — A brief progress report of different investiga- 

 tions with vegetables for the year ended June 30, 1915. 



The work with tomatoes, asparagus, and cabbage was continued. The cul- 

 tural experiments with cabbage have been published in Bulletin 137 (E. S. R., 

 34, p. 636). Little progress has been made in the breeding work with early 

 cabbage because of the difficulty experienced in successfully wintering the 

 plants. Prom certain plants successfully carried through the winter line- 

 bred seed was not secured because the flowers proved sterile to their own 

 IX)llen. When the blossoms were fertilized with pollen from a sister plant a 

 large amount of seed was secured. 



Breeding work with tomatoes (E. S. R., 35, p. 235), although yet incomplete, 

 shows the importance of considering the plant as the nnit of selection. At the 

 same time it has shown that not all plants of superior appearance are able to 

 transmit their superior characteristics to their progeny. As a result of work 

 conducted for three years strains have been isolated which appear to possess 

 superiority to the best of commercial strains in respect to earllness, produc- 

 tiveness, and general character of fruit. 



The variety test with asparagus which has been in progress for the past 

 six years shows the superiority of Palmetto to other varieties tested. The 

 planting of large healthy asparagus crovms as compared with smaU crovms 

 has resulted in an increase in monetary value of more than $100 an acre. 

 Another experiment has shown the superiority of 1-year-old as compared with 

 2-year-old crowns. 



[Report on horticultural investigations at the Beeville substation, 1910- 

 1914], E. B. BiNFOBD (Texas Sta. Bui. 214 (1917), pp. 19, 20-26, 27, figs. S).— 

 The results of tests and experiments vdth vegetables are presented and recom- 

 mendations are made relative to the best varieties and methods of culture. 



Observations made on a number of varieties of citrus fruits grown at the 

 substation indicate that the Dugat and Satsuma oranges are the best varieties 

 for the section and make very satisfactory yields. The lemon is not a satis- 

 factory crop. The pomelo is less frost resistant than the orange but produces 

 well. The Duncan, Pemambuco, and Royal varieties are especially recom- 

 mended. The kumquat is very successful. Beeomm«idations are given for 

 the management of citrus orchards.
