suited for this work. Considerable difference was noticed in the killing power 

 of different samples of lead arsenate and in their action upon the foliage. Thorough 

 spraying is needed in order to cover all parts which may be attacked by the codling 



moth. 



Since the broods seem to overlap one another without leaving any interval between 

 them, it is considered necessary to spray at short intervals from April until October. 

 The author suggests 9 applications during the season on April 10 and 30, May 17, 

 June 17, July 10, August 1 and 21, September 12, and the first week of October. 

 These applications may be expected to yield a crop of apples from 95 to 98 per cent 

 free from codling moth, at a total cost of about 32 cts. per tree. 



The gypsy moth in New Hampshire, E. D. Sanderson (New Hampshire Sta. 

 Jlnl. 121, pp. 81-104, figs. 11). — The history of this moth in Massachusetts is briefly 

 i mt lined and notes are given for the purpose of comparing the life history of the gypsy 

 moth and brown-tail moth. In 1904 an examination of the southeast coast of New 

 Hampshire showed that the gypsy moth was present in small numbers in all of the 

 towns from the Massachusetts line to Portsmouth. A map is given showing the 

 present distribution of the gypsy moth in New Hampshire. The life history, habits, 

 food plants, natural enemies, and methods of combating this pest are described. 



The brown-tail moth in New Hampshire, E. D. Sanderson (New Hampshire 

 Sta. Bui. 122, pp. 105-132, figs. 20). — This moth was first recognized in Massachusetts 

 in L890 but did not attract attention until 1897. It has spread with great rapidity, 

 and in 1899 was first found in New Hampshire in the town of Seabrook. At present 

 it is distributed over all of the southeastern part of the State. The life history, 

 habits, and practical methods of combating this pest are described. Notes are also 

 given on its natural enemies and on the injury caused by the nettling hairs of the 

 caterpillar. 



The gypsy moth and the brown-tail moth, W. E. Britton ( Connecticut State 

 Sta. Bui. 153, j>j>. 11, figs. 8). — The gypsy moth has been found at Stonington, Con- 

 necticut, and an attempt is being made to eradicate it. A brief account is presented 

 of the habits and life history of the gypsy moth and brown-tail moth with practical 

 methods of controlling these pests. 



Some experiences with insecticides for the San Jose scale, C. O. Houghton 

 (Delaware Sta. Bid. 74, pp. 16). — A considerable variety of proprietary remedies were 

 used as well as kerosene emulsion and lime-sulphur-salt washes. The applications 

 were made for the most part in the spring but in ordinary instances in the fall. 



Peach trees were sprayed with a mixture containing 15 lbs. each of lime, sulphur, 

 and salt per 45 gal. of water boiled by steam for i hour. Various other formulas for 

 the lime-sulphur-salt wash were tested, both for boiling by steam and for self-boiling 

 caustic washes. Trees sprayed in the fall when examined during the next spring 

 showed no living scales in the case of those which had been treated with the boiled 

 wash and only a few of those treated with the unboiled wash. Both forms of the 

 wash had largely been washed off the trees by February 13, little difference being 

 observed in the adhesive power of the boiled and unboiled washes. 



The chief advantage of using oil sprays is that these materials spread more rapidly 

 over the trees but they have the disadvantage that it is not readily apparent whether 

 all parts of the tree have been covered or not. The lime-sulphur washes gave satis- 

 [actory results in all cases and the author, therefore, recommends their use as well as 

 that of kerosene emulsion. 



The San Jose scale, W. Newell (Crop Pest Com. La. Circ. 4, pp. 42, figs. 15). — 

 The introduction and spread of the San Jose scale in Louisiana is attributed to the 

 fact that no quarantine system against fruit-tree pests has been in operation in the 

 State until recently. 



The San Jose scale is described in its various stages and historical notes are given 

 on the distribution of the pest and upon its food plants. An account is also presented
