The advent of this fleet of boats to the mouth of the creek is in the highest degree exciting. As boat after boat rushes into the river, there is the dashing to and fro of the boatmen, and the shouts of the multitude on the shore. Here and there a collision occurs that often results in the crushing of the feebler boat, and the indiscriminate mingling of boatmen, fragments of the broken craft, oil, and fixtures in one common ruin. In this fleet the form and variety of boats beggars all description. Sometimes there is the orthodox flatboat, filled with iron-bound barrels, with an air of respectability hovering around it. Next will follow a rude scow, and close upon it an unwieldy 'bulk,' into which the oil has been pumped at the well. After this, perhaps, may be seen a rude nondescript, that surely was never dreamed of outside the oil region. It consists of a series of rough ladders, constructed of tall saplings. Between each pair of rounds in these ladders is placed a barrel of oil, floating in the water, but kept in position by its hamper. A number of these ladders are lashed together, until the float contains two or three hundred barrels of oil. The bulks spoken of are about sixteen feet square and two or three feet in depth, divided internally into bulk-heads of perhaps four feet square, to prevent any undue agitation of the oil by the motion of the boat, and are sometimes decked over. These unpromising boats, as well as the ladder floats, are, during favorable weather, often run to Pittsburg with entire safety. Steamboats, however, run up to the mouth of Oil Creek during the time of high water, and afford the safest and most expeditious means of transportation.
