In all, says Mr. W.L.  McAtee, thirty-six species of birds of thirteen families help man in his irrepressible conflict against his deadly enemy, the codling moth.  “In some places they destroy from sixty-six to eighty-five per cent of the hibernating larvae.”

Now, are the farmers of this country content to let the Italians of the North, and the negroes of the South, shoot those birds for food, and devour them?  What is the great American farmer going to do about this matter?  What he should do is to write and urge his members of Congress to work for and vote for the federal migratory bird bill.

THE COTTON BOLL WEEVIL.—­Let us take one other concrete case.  The cotton boll weevil invaded the United States from Mexico in 1894.  Ten years later it was costing the cotton planters an annual loss estimated at fifteen million dollars per year.  Later on that loss was estimated at twenty million dollars.  The cotton boll weevil strikes at the heart of the industry by destroying the boll of the cotton plant.  While the total loss never can be definitely ascertained, we know that it has amounted to many millions of dollars.  The figure given above has been widely quoted, and so far as I am aware, never disputed.

Fortunately we have at hand a government publication on this subject which gives some pertinent facts regarding the bird enemies of the cotton boll weevil.  It is Circular No. 57 of the Biological Survey, Department of Agriculture.  Any one can obtain it by addressing that Department.  I quote the most important portions of this valuable document:
