labor, but do not include cost of engineering, depreciation and interest on 

 cost of forms and plant. These items would be small for the work was 

 done under the supervision of the superintendent of the company who is 

 paid largely for other duties, and the cost of forms and plant was small. 

 The wages and cost of cement are low and the canal was easily accessible, 

 making the cost of lining lower than could be obtained in British Columbia. 

 On the system of the Fruitlands Irrigation and Power Company, near 

 Kamloops, the cost of lining 12,000 feet of canal 4 feet wide at the bottom, 



3 V 2 feet deep, and 7 * feet wide at the top with 3 inches of concrete aver- 

 aged as follows: 



Hauling forms, placing forms, backfilling with earth forms.. $ .18 per lineal foot 



Cost of cement 50 " " " 



Cost of sand and gravel 16 " " " 



Cost of placing concrete forms, mixing and placing concrete .30 " " " 

 Gasoline for concrete mixers 01 " " 



$1.25 



Cost per lineal foot, including backfilling, $1.25. 

 Cost per square foot, including backfilling, $0.105. 



The concrete used was a mixture of 1 part of cement to 3 of sand and 



4 of gravel. The cement cost $3.40 delivered on the job. The above cost 

 was obtained where the canal was easily accessible along the foothills and 

 the forms and concrete mixer could be easily moved along the banks of the 

 canal. The cost of engineering, administration, interest and depreciation 

 on cost of plant are not included in the cost. 



On several thousand feet of canal where the canal was excavated on a 

 steep rocky side hill, it was very difficult to deliver the concrete and the 

 total cost of the above items was $1.72 per lineal foot or 14^ cents per 

 square foot. 



On the system of the Kelowna Irrigation Company, which has about 12 

 miles of lined canal, no separate form was used for backfilling the earth; 

 instead metal plates were held away from the concrete forms by studding 

 of the thickness of the concrete inserted between concrete forms and the 

 plate as described above. The cost of lining 24,000 feet of main canal, 3 

 feet wide at the bottom, 2^ feet deep, and 5^ feet wide at the top gave 

 the following average cost: 



Making rock drain below floor, hauling forms, placing forms 



and backfilling $ .21 per lineal foot 



Cost of cement and hydrated lime 47 " " " 



Cost of sand and crushed rock 16 " " " 



Mixing and placing concrete 49 " " 



Miscellaneous 03 " " " 



Cost per lineal foot $1.36 



Cost per square foot 158 



The concrete was a mixture of 1 part of cement to 3 of sand and 5 of 

 crushed rock. Cement cost $3.20 to $4.10 delivered. The wages were 

 $2.75 per day of 10 hours for common labor and $3.50 to $5.00 for skilled 

 labor. The cost of engineering, which included location of the canal and 

 the cost of depreciation and superintendence, brought the total cost to 

 17.73 cents per square foot. As the cost of lining only is considered here the 

 cost of location should not be added. The higher cost per square foot ob- 

 tained in this case was due to the higher cost of cement, the necessity for 

 building roads to deliver material and move forms and mixer aleng the
