The greatest goodis done in the destruction of field-mice, which doso much damage to the grass roots, to the grain bothwhen stacked and in the shock, and to young fruit- 305 3o6 The Screpch Owl trees.

They are particularly plenti-ful about hedgerows, brush heaps, stone piles, hayand grain stacks, and farm buildings, while theorchard is one complete network of them.
