Leaving Shanhaikwan at 5:20 in the morning and reaching Mukden at 6:30 in the evening, we rode the entire day through Manchurian fields. Manchuria has an area of 363,700 square miles, equal to that of both Dakotas, Minnesota, Nebraska and Iowa combined. It has roughly the outline of a huge boot and could one slide it eastward until Port Arthur was at Washington, Shanhaikwan would fall well toward Pittsburgh, both at the tip of the broad toe to the boot. The foot would lie across Pennsylvania, New York, New Jersey and all of New England, extending beyond New Brunswick with the heel in the Gulf of St. Lawrence. Harbin, at the instep of the boot, would lie fifty miles east of Montreal and the expanding leg would reach northwestward nearly to James Bay, entirely to the north of the Ottawa river and the Canadian Pacific, spanning a thousand miles of latitude and nine hundred miles of longitude.
The Liao plain, thirty miles wide, and the central Sungari plain, are the largest in Manchuria, forming together a long narrow valley floor between two parallel mountain systems and extending northeasterly from the Liao gulf, between Port Arthur and Shanhaikwan, up the Liao river and down the Sungari to the Amur, a distance of eight hundred or more miles. These plains have a fertile, deep soil and it is on them and other lesser river bottoms that Manchurian agriculture is developed, supporting eight or nine million people on a cultivated, acreage possibly not greater than 25,000 square miles.
Manchuria has great forest and grazing possibilities awaiting future development, as well as much mineral wealth. The population of Tsitsihar, in the latitude of middle North Dakota, swells from thirty thousand to seventy thousand during September and October, when the Mongols bring in their cattle to market. In the middle province, at the head of steam navigation on the Sungari, because of the abundance and cheapness of lumber, Kirin has become a shipbuilding center for Chinese junks. The Sungari-Milky-river, is a large stream carrying more water at flood season than the Amur above its mouth, the latter being navigable 450 miles for steamers drawing twelve feet of water, and 1500 miles for those drawing four feet, so that during the summer season the middle and northern provinces have natural inland waterways, but the outlet to the sea is far to the north and closed by ice six months of the year.
