Mr. J. W. Manning says in Boston Cultivator:

I will here record my own experience: In 1858, 3-feet trees of Norway spruce and Scotch larch were planted. In 9 years the spruce reached 15 feet in height and- spread 12 feet broad, and was then successfully transplanted. The larch in 1872 had reached 30 feet, and had a spread of branches full 20 feet, and a circumference of 4 feet at the base. One larch had attained 40 feet from 5 feet, in 17 years, and this on the dry, sandy loam, that was distinguished for barrenness 20 years ago, so that only a medium crop of rye could be grown once in 5 years. I have grown rock maple trees from the seed on the same sort of land in 6 years to 15 feet high and 2\ inches in diameter. The white maple excels many others in rapid growth. From 6-feet trees, 3 years from seed, planted in the fall of 1864, they now stand 35 feet, and are from 7 to 10 inches in diameter at base. All these are on naturally poor soil that has been kept free of weeds and grass. I planted elms in 1856 that were easily carried on my shoulder, and now they stand 30 to 40 feet high, with a girth at base of 6 feet. Rock maples planted in 1855 stand now 30 feet high and 15 inches in diameter. The bass and white ash I then planted have done as well in the race of life.

So with such living examples to behold, and as good or better examples in all towns, an enthusiasm could be generated that would shortly line all our streets and country roads with comforting shade. I know of a farm in Lisbon, N. H., Leonard Bowles's, on which were planted, 30 years ago, rock maples on the roadside as far as his land extended, and the result is, that hill on which these trees stand is memorable in the life of the planter. Those trees are distinctly visible from the top of Mount Washington, which is more than 20 miles to the east. It is very strange that more land owners do not appreciate such examples often seen in communities, and plant miles of trees, leaving a growing monument, instead, as is frequently the case, leaving a more desolate aspect to the land than they found.
