They do not pile the slashings and hence expose the timber tracts to fire dangers.

They convert young trees into hewed crossties which would yield twice as great a return if allowed to grow for four or five years longer and then be cut as lumber.
Just to show how a small tract of trees will grow into money if allowed to mature, the case of a three-acre side-hill pasture in New England is interesting.

Forty-four years ago the farmer who owned this waste land dug up fourteen hundred seedling pines which were growing in a clump and set them out on the sidehill.
Twenty years later the farmer died.

His widow sold the three acres of young pine for $300.

Fifteen years later the woodlot again changed hands for a consideration of $1,000, a lumber company buying it.
