U.S.A. INVESTIGATIONS.

Grammar Schools belong ; also the work was considered so satisfactory 
that an account of it, written by Mr. Bailey to his Grace the Duke of 
Westminster, was read by the Hon. Cecil Parker before one of the 
Committees of the Royal Agricultural Society of England in 1887, and 
recommended for publication. Further, in giving knowledge of 
common farm insects, the plan adopted by the Head Master (I have 
pleasure in saying with endeavours to help by myself) has answered 
so exceedingly well in giving the boys a serviceable knowledge of farm 
crop insect-pests and their prevention that, as I have before mentioned, 
the Dominion Entomologist of Canada, Mr. J. Fletcher, wrote over for 
details of the plan followed. I have ventured to draw attention to this 
as an example of a real, practically successful plan of instruction on 
one branch of agricultural knowledge, laid on the foundation of the 
practical observations of the students to start with. 
During 1889 the British observations on Warble-attack bore good fruit 
beyond their special service in this country, by suggesting investigation 
in the United States of America relatively to damage caused there also 
by Warble-maggot, of which I append some notes, as the two countries 
are mutually interested in amount of prevalence and methods used for 
prevention of this infestation, which is easily transmissible in shipped 
cattle. Circulars were sent by the Proprietors of the ‘ Farmers’ 
Review,’ of Chicago, under the superintendence of their Editor, 
Mr. A. S. Alexander (see also p. Ill), to those interested in the subject 
over (as will be seen below) an enormous area of stock-producing 
country, and in reply much information was forwarded. Much of this 
was valuable, some not so, but when sifted and arranged the reports 
are well worth attention. These will be found at length in the 
numbers of the ‘Farmers’ Review’ noted below,* and an abstract of 
these reports was published in the U.S.A. Department of Agriculture 
Bulletin, entitled ‘ Insect Life,’ for November, 1889. 
The following extract from this gives percentage of cattle attacked, 
and loss on hides in the more especially cattle-rearing States; and 
when it is borne in mind that the collective extent of the eight States 
which are noticed as specially infested amounts to about 422,500 
square miles, the importance of the loss speaks for itself. 
“A host of letters from farmers and stock-men were published . . . 
Reports were also received from professors of agriculture, entomolo¬ 
gists, and veterinarians, which give, as did also those of farmers and 
stock-raisers, valuable data concerning its abundance in various States, 
the loss in value to hides, effect on quantity and quality of beef and 
milk, and also the effect of the attacks on the animals themselves.
