The water continued rising throughout the night, and about noon of Sunday reached its maximum, three feet six inches above high-water mark of 1877, which was the highest on record. At that time the city presented a strange spectacle. Pennsylvania avenue, from the Peace monument, at the foot of the Capitol, to Ninth street, was flooded with water, and in some places it was up to the thighs of horses. The cellars of stores along the avenue were flooded, and so were some of the main floors. In the side streets south of the avenue there was six to eight feet of water, and yawls, skiffs and canoes were everywhere to be seen. Communication except by boat was totally interrupted between North and South Washington. At the Pennsylvania Railroad station the water was up to the waiting-room. Through the Smithsonian and Agricultural Department grounds a deep stream was running, and the Washington Monument was surrounded on all sides by water. A dozen lives lost, a hundred poor families homeless, and over $2,000,000 worth of property destroyed, is the brief but terrible record of the havoc caused by the floods in Maryland. Every river and mountain stream in the western half of the State has overflowed its banks, inundating villages and manufactories and laying waste thousands of acres of farm lands. The losses by wrecked bridges, washed-out roadbeds and land-slides along the western division of the Baltimore and Ohio Railroad, from Baltimore to Johnstown, reach half a million dollars or more. The Chesapeake and Ohio Canal, that political bone of contention and burden to Maryland, which has cost the State many millions, is a total wreck. The Potomac river, by the side of which the canal runs, from Williamsport, Md., to Georgetown, D. C., has swept away the locks, towpaths, bridges, and, in fact, everything connected with the canal. The probability is that the canal will not be restored, but that the canal bed will be sold to one of the railroads that have been trying to secure it for several years. The concern has never paid, and annually has increased its enormous debt to the State. The Western Maryland Railroad Company and the connecting lines, the Baltimore and Harrisburg, and the Cumberland Valley roads, lose heavily. On the mountain grades of the Blue Ridge there are tremendous washouts, and in some sections the tracks are torn up and the road-bed destroyed. Several bridges were washed away. Dispatches from Shippensburg, Hagerstown and points in the Cumberland Valley state that the damage to that fertile farming region is incalculable. Miles of farm lands were submerged by the torrents that rushed down from the mountains. Several lives were lost and many head of cattle drowned. At the mountain town of Frederick, Md., the Monocacy river, Carroll creek and other streams combined in the work of destruction.
