He states: "that during the grasshopper visitations of 1875 and 1876, his fields, surrounded by timber belts (whether from cause or accident), escaped almost uninjured." Hon. J. G. Knapp, of Wisconsin, confirms this statement, by saying that the presence of forests not only intercepts the progress of insects, but prevents the spread of contagious and destructive fungi. In Iowa the chinch bug destroyed in many localities last year, the entire wheat crop. The authority above quoted, declares that these pests can never traverse a belt of thick timber, seven or eight rods in width, to devastate an adjoining field. The cool, damp soil and shade of such a belt constitute an impassable barrier to their march. The value of crops destroyed the last few years by chinch bugs and grasshoppers, would be nearly sutficient to plant belts of timber around every farm in the State. Rust in wheat is a species of fungi, which in virulent form is borne on the wind and blights and destroys all grain with which it comes in contact. A farmer in the east states that out of 200 acres of promising wheat growing on his farm, all were destroyed by rust, except those sheltered by woods. _ The benefit of the presence of wood lands and timber belts to arrest the storms and blasts of winter is incalculable. Timber for fuel and economic purposes is a question of immediate necessity. The profits to be derived therefrom, though somewhat remote, are none the less real.
