Dr. L. W. Puffer tells the people of Brockton, N. Y., that it is absurd to select a tree that will have a span of head 40 feet, and then plant them but 10 feet apart. About three times as many trees are set out along the streets as should be set - all of which is as true everywhere as at Brockton. Trees are also set often too near dwellings. He thinks such cities as Brockton should have a city forester to see that trees are properly set and treated afterwards. On account of the bad judgment of the early planters many trees must now of necessity come down, and he fears the city will soon be without street trees of any kind.
