Note — In the above table, Factor = a/100, in which a is the land area adjacent to a rainfall station, nnd the 
factor is to convert the observed rainfall at the station in inches of depth to units of 100 inch-miles on the 
land drainage area adjacent to the rainfall station. 
The total land part of the drainage area of Lake Michigan-Huron shown, 92,493 square miles, was the best 
value obtainable at the time. 
shore were used for estimating the rainfall on both the land and lake areas. The 
corresponding list of stations for the Lake Superior land drainage area is given in 
Table 6, and the locations of the stations are shown on Plate 4. 
The factors shown in Tables 5 and 6 convert the observed rainfall at the station 
in inches of depth to units of 100 inch-miles on land, an inch-mile being defined as

Note — In the above table, Factor = a/100, in which a is the land area adjacent to a rainfall station, and the 
factor is to convert the observed rainfall at the station in inches of depth to units of 100 inch-miles on the land 
drainage area adjacent to the rainfall station. 
It has been subsequently discovered that the above table of stations and factors is not the one used in this 
investigation. A thorough search for the one actually used proved futile. Incidentally this is the only piece of 
computation definitely known to be lost at the time of publishing this material, fourteen years after labors were 
begun upon it.
