" The data presented point out, it is believed, the practicability of destroying 

 the San Jose scale on apples and suggests the desirability of the adoption of 

 the practice of fumigation by exporters if such treatment will result in the 

 acceptance by foreign countries of fruit so treated. A certificate of proper 

 fumigation on each . barrel, box, or package should constitute a sufficient 

 guaranty that any scales present had been killed. It is considered probable 

 that, if desirable, fumigation could be practiced in the case of numerous fruits, 

 as pears, oranges, lemons, etc. In the fumigation of apples in barrels it 

 \A'Ould appear sufficient to remote the upper head only, or to use for the original 

 heading boards with numerous i or 1 in. auger holes — a total of 15 or 20 at 

 each end." 



There are appended synopses of the laws and decrees in force in foreign 

 countries bearing on the introduction of live plants and fresh fruits, and of 

 the laws and regulations of the various States in this country bearing on the 

 transportation and sale of fresh fruits infested with San Jose scale or other 

 Injurious insects. 



Important insecticides: Directions for their preparation and use, C. L. Mar- 

 LATT ([/. 8. Dept. Agr., Farmers' Bui. 127, rev., pp. .'/S, figs. 7). — In this second 

 revision there are some changes of old formulas, necessitated by the important 

 additions to our knowledge of insecticides since the last revision, in 1903. 



Methods of exterminating the Texas fever tick, H. W. Geaybill ( U. S. Dept. 

 Agr., Fanners' Bui. 378, pp. 30, figs. 15). — Information of practical value relat- 

 ing to the cattle tick, including data from investigations personally conducted, 

 has been brought together in 'this publication. 



Following a brief description of the life history of the cattle tick, the methods 

 of eradication are taken up and discussed at some length. Tables are given 

 which show the time required to free i)astures from ticks by starvation, and 

 the time requii'ed for all ticks to drop from cattle placed on tick-free land. 

 Methods of rotation by which cattle and pastures may be freed from ticks in 

 4, 4i, and 8 months are described and illustrated by figures. The destruction 

 of ticks by dipping, spraying, and hand dressing is considered, directions being 

 given for the preparation and use of crude petroleum, emulsions of crude petro- 

 leum, and the arsenical dip. Specifications and materials for a dipping vat 

 which will hold 2,0SS gal. are accompanied by drawings, and the bill of mate- 

 rials for the vat and draining pens.
