 19.6 per cent in Delta, and 6.7 per cent in Montrose. Of all other 

 crews, which include 1-2 crews, 4-2 crews, etc., 2.04 per cent are

Table XVII gives a general idea of the practice, while Tables 

 XVIII and XIX give detailed data on the efficiency of the 3-2 

 crew as compared with the 2-2 crew, which is shown to be fully as 

 efficient as the 3-2 crew. This is because ordinarily the third man 

 of the 3-2 crew is a driver and does not handle an extra lead of hose. 

 Thus there are usually only two leads of hose, whatever crew is used. 

 Table XX summarizes the efficiency data for the 3-2 and 2-2 crews.
