THE FLOOD OF 1 843. 83 



A flat between the West branch dam breast and the fac- 

 tory, has a deposit of coarse sand and gravel, averaging 

 nearlj^ two feet in depth, and covering more than half an 

 acre. Another flat opposite Crozerville factory, is covered 

 with rocks, stones, and gravel, to the extent of more than 

 two acres, and the creek at the same place, which flowed here- 

 tofore in a bed flanked by banks of from four to six feet high, 

 has entirely changed its channel — the old bed being filled up 

 with stones and coarse gravel, so as to form a surface level 

 with the former banks. On the opposite side, and in the 

 forks of the creek, as has been before mentioned, a deposit of 

 mud four or five inches deep, covers a lot of three-fourths of 

 an acre, while large beds of sand are piled up in various 

 places. The annexed cut (next page) will serve to illustrate 

 the relative situation of these deposits. The cause of the 

 deposits of mud being made at this point, is sufticienth^ 

 explained in another part of the report. The largest rock 

 noticed, the resting place of which had unquestionably been 

 changed by the flood, was one near Crozerville dam. This 

 rock is estimated to weigh from ten to twelve tons, and was 

 removed a distance of four or five rods. Its former position 

 was well known, but what confirms the fact of its removal 

 beyond a single doubt, it was found resting against and upon 

 another rock with a piece of domestic goods between the two. 



Below the junction of the two streams in the vicinity of 

 Pennsgrove and Rockdale, the changes produced are very 

 striking. The valley of the creek, in many places to a con- 

 siderable width is entirely divested of its surface, while in 

 other parts it is strewed with gravel, stones and rocks, many 

 of them of an enormous size. What is most strange, persons 

 residing in the neighborhood, are at a loss to tell where all 

 these rocks and stones were brought from. Many materials 

 from this vicinity, composed wholly or nearly altogether of 

 iron, were in many instances carried to great distances. An 

 iron boiler weighing over seventeen hundred weight, was car- 

 ried from Mr. Crozer's West branch factory, and lodged in
