 Wooster. Red and alsike clovers are most seriously injured, while 

 Trifdium rejyens (white clover) suffers less. Probably all species 

 belonging to the genus Trifoliimi may serve as food-plants,

This is a report on a three months' journey in the United States 

 made on the initiation of Dr. L. 0. Howard, the expenses of which were 

 defrayed by ]\Ir. A. Carnegie. The itinerary outwards was from 

 Boston to San Francisco and homewards through Los Angeles, Arizona, 

 New Mexico, Kansas and Texas to New Orleans, thence through the 

 eastern States to New York and Boston, the various agricultural 

 stations being visited en route. After a general survey of the relations 

 between applied science and agriculture in the United States and an 

 account of the U.S. Department of Agi'iculture, and its publications, 

 the Bureau of Entomology and its staff and work are described, with 

 details as to the methods used in special investigations, abundantly 

 illustrated by photographs. A description of the research work in 

 progress at the time of the visit is given, with a survey in considerable 

 detail of the more important investigations and the results obtained. 

 The Bureaus of Plant and Animal Industry are fully dealt with. 

 The general organisation of the State Agricultural Experiment Stations 

 is given, with a statement of the special work which has been 

 done by some of them. The work of the State Commission of Horti- 

 culture and the Quarantine Division of California and that of the 

 Massachusetts Forest Service is noticed, and the organisation of the 

 control of the gipsy and bro"v\ii-tail moths appears to have greatly 

 impressed the author. A chapter is devoted to the organisation of 

 the Universities of the United States, more particularly in relation to 

 the scientific work undertaken bearing upon entomology. The 

 Agricultural Colleges and Associations and Societies interested in 

 kindred matters are briefly noticed. Some 70 pages are devoted to an 

 account of the general methods employed for the study and control of 

 insect pests of man, animals and agi-iculture, illustrated by some 

 important examples ; the preparation and mode of use for various 

 purposes of Bordeaux mixture and lime-sulphur and other insecticides, 

 poisoned baits and methods of soil disinfection are described and the 

 methods of fumigation with hydrocyanic acid and the apparatus used, 

 receive special mention. The report concludes with a short account 

 of the Plant Quarantine Act and its administration by the Federal 

 Horticultural Board and of the good effect of the " Insecticide Act " 

 and the State Legislation which has resulted from it. In a final 

 chapter the author expresses his admiration of the organisation of 

 the U.S. Department of Agriculture and, whilst recognising that the 

 great size of the country demands special measures, he considers that 

 there is much in it which might be imitated in the smaller areas of 

 Europe.
