Histohy Sikvky by thick, deeply rissured. broad-ridged, ashy-gray bark, attains a diameter of 2y2 to 3 feet, and the height of the tree is often between HO and 100 feet. Dislnbution: On bottomlands, stream banks, and springy hills, the \Miite Elm ranges from Newfound- land far west into Canada and south to Florida and Texas. It is found practically throughout Illinois and reaches its largest size as well as its greatest abundance in the southern counties. In the upland type of mixed hardwood forest it is found at the rate of about 2 trees per acre; amongst the Post Oaks and Scrub Oaks it does not occur; but in the bottomlands it averages 8 trees per acre in the Cy- press forests, 13 to 14 trees per acre along the main streams, and fi trees per acre along the secondary streams. The largest measured tree was KK feet high and 35 inches in di- ameter. One near Ware, Union County, though only GO feet tall, was 30 inches in diameter and had a clear bole 4:2 feet long, from which 921 board feet of lumber could be taken. In the Wabash Valley a White Elm was seen 95 feet tall, though the trunk diameter was only 15 inches; but on the Kaskaskia bottoms the highest tree measured 80 feet, with a diameter of 32 inches; while in the north, along the Rock River, a tree was found which was 90 feet high and 30 inches in diameter. On the u])lands of Union County the average height is 50 feet and the average diameter 97^ inches. Robert Ridgway says that fully 90 per cent of the trees in the W'a- bash \'alley that are attacked by mistletoe are White Elms. I'scs: The white, hard wood of the American Elm is moderately heavy and tough, but it is apt to twist and warp unless it is handled â carefully in seasoning, and it is not durable in the soil. It is used in making barrel staves, wagon hubs, cheap furniture, veneer for fruit baskets, and sometimes for the bows of carriage-tops. In 1925. some ,000 board
