taining the blacksmith shop. Based upon the above figures the 
summarized cost of one team per calendar day is as follows: 
Interest on cost of team at 6 per cent per year $0. 098 
Depreciation of a team at 10 per cent per year 164 
Interest on cost of harness at 6 per cent per year 007 
Depreciation of harness at 25 per cent per year 027 
Feed and bedding 1. 057 
Total cost per calendar day 1. 353 
The records of the camp show that up to August 10 maintenance 
was provided for 2,351 team days, and the following table shows the 
number of team days actually employed and lost : 
Number of team days employed 1, 661. 
Number of team days idle 244. 5 
Number of team days lost by sickness . ' 77. 5 
Number of team days lost by Sundays and holidays 368. 
Total team days to Aug. 10 2, 351. 
It is evident, therefore, that the team days actually employed 
formed only 70.7 per cent of the total number for which maintenance 
was provided, and the cost of a double team and harness per actual 
working day therefore was 
1.353^-0.707=$1.91. 
All work teams were driven by convicts except that part of the 
time of the one free driver which was spent on the road work.
