Runoff of Muskingum river. In table No. 42 is given, the rain- 

 fall and runoff record for Muskingum river, Ohio, as measured at 

 Zanesville, 1 for the years 1888 to 1895, inclusive, the area of i he 

 catchment above the point of measurement being 5828 square 

 miles. The headwaters of the stream are not far from Lake Erie 

 and on the dividing line between the hill country of the east and 

 the prairie country of the Mississippi valley. Hence this stream 

 represents conditions applicable to the runoff of the Ohio streams 

 tributary to Lake Erie. The rainfall- record as used in this table 

 is the mean of the records kept at Akron, Canton, Newcomers- 

 town and Wooster, and may be considered to represent fairly well 

 the mean precipitation of the Muskingum catchment area. For 

 the year 1892 the total rainfall was n.74 inches and the total 

 runoff 13.38 inches', of which 9.0(1 occuirred in the storage period. 

 In 1893 the total rainfall was 4l\: > >(> inches, with a total runoff 

 of 16.20 inches, the runoff of the storage period being 14.13 inches.
