We do not believe it is desirable to prune the feathery growths often found on the trunks of elms, as they are apparently protective in nature ; moreover, in our estimation they add to the. Fig. 3.

As a rule the limbs on vigorous maple trees will droop about one foot or more a year owing to their increased weight, and it is only a short time before they become too low. Limbs over a sidewalk may be left lower than over roadways. During rain and sleet storms limbs are heavily weighted and often give trouble when too near the ground. On country roadsides pruning should be high enough so that the limbs will not interfere with the hay and wood traffic which is com-.
