not control the lands which environ their trees, 
and when snow falls to a considerable depth 
prompt measures are sometimes necessary to 
keep mice from destroying them.

dragging a heavy log several times around each 
block of trees, packing the snow so firmly that 
mice cannot tunnel under it. If this be done 
promptly after the first snowfall, subsequent 
falls will require little attention. Under no 
circumstances should matted grass or litter be

snow a cleared space of about 18 inches radius
