A correspondent in Livingston, Illinois, reports that the planting of trees in groves and shelter-belts, and for ornamental purposes, has become very general in that county. Ten years ago 95 per cent, of the area of the county was treeless; but now a farm without a grove is an exception to the general rule. Black walnut has the preference for profit and ease of cultivation; but elm, soft maple, willow, cottonwood, European larch and ash are common, while evergreens are popular for ornamental purposes,and occasionally are planted in groves and shelter-belts.- Dep. of Agricidture.
