METHODS OF COMMUNICATION FOR FOREST PROTECTION 



In preparing an estimate for a telephone line, the costs should be classified under 

 the heads shown in the following schedule: 



Estimating Cost of Pole Lines 

 (a) Survey of route. 

 (&) Tools. 



(c) Line materials. 



(1) Wire. 



(2) Insulators, brackets, and nails. 



(3) Poles. 



(4) Guys, braces and miscellaneous. 



(d) Station materials. 



(e) Transportation. 



(1) Wire and miscellaneous supplies. 



(2) Poles. 



(3) Camp moving. 

 (/) Line clearing:. 



(1) Cutting. 



(2) Burning. 



(g) Line construction. 



(1) Digging holes. 



(2) Setting poles. 



(3) Pulling 'wire. 



(4) Tying in. 



(5) Miscellaneous adjustments, guys, etc. 

 (ft) Station installations. 



(1) Outside work. 



(2) Inside work. 



2 Estimating Costs of Tree Lines 

 (a) Survey of route. 

 (&) Spotting trees. 



(c) Tools. 



(d) Line materials. 



(1) Wire. 



(2) Insulators and staples. 



(3) Miscellaneous and poles (if any), 



(e) Station materials. 

 (/) Transportation. 



(1) Wire and insulators. 



(2) Camp moving. 

 (g) Line clearing. 



(1) Cutting. 



( 2 ) Burning. 



(h) Line construction. 



(1) Pulling wire. 



(2) Tying in. 



(3) Pulling slack. 



(4) Setting poles (if any). 

 (i) Station installation. 



(1) Outside work. 



(2) Inside work. 



2 APPROXIMATE COSTS OF SUPPLIES AND AVERAGE TIME REQUIRED FOR VARIOUS OPERA- 

 TIONS IN TELEPHONE LINE CONSTRUCTION 



'All figures based on quotations in Prairie Provinces prior to the European War) 



1 Supplies 



(a) Tools (per ten-man crew). 



(1) For pole line, $200. 



(2) For tree line, $120. 



(3) For station work, $25. 

 (&) Line materials (per mile). 



(1) Wire, No. 9 B.W.G., $12. 



(2) Insulators, etc., $2. 



(3) Poles, 25 feet, $18 up. 



(4) Miscellaneous, $1 up. 

 (c) Station materials each, $15. 



2 Transportation 



This is a cost that depends so much on local 

 condition that no average figure has any 

 value. The weight to be transported 

 may be determined from -the lists in 

 Appendix A. 

 3 Spotting Trees 



(a) Very open timber 2 men, 2 miles per 



hour. 

 (&) Very dense timber 3 men, i mile per 



hour. 

 4 Line Clearing 



This is a cost that depends entirely on local 

 conditions. In general, right of way for 

 tree lines should seldom cost over $25 per 

 mile for clearing, with labour at 30 cents 

 per hour, but under exceptionally un- 

 favourable conditions may run to $45 per 

 mile. In fair-sized timber with little 

 underbrush the cost may be as low as $2 

 per mile. For pole lines the cost will be 

 materially higher, depending on the 

 width of clearing. 



5 Line Construction, Tree lines 

 (a) Pulling wire. 



(1) Best 2 men and 1 horse, 1 mile 



per hour. 



(2) Worst 5 men, J mile per hour. 

 (6) Tying in. 



(1) Best 1$ miles per man, per day. 



(2) Worst \ mile per man, per day. 



(c) Pulling slack 2 men, 1 mile per hour. 

 On pole lines all these costs will be reduced 



from 15 to 50 per cent. 



6 Erecting Poles, 2>2J or 2>5 feet 

 (a) Digging holes. 



(1) Soft ground 1 man, 3 holes per 

 hour. 



(2) Medium ground 1 man, 1'hole per 

 hour. 



(3) Hard ground 1 man, hole per 

 hour. 



(&) Setting poles 3 men, 2J poles per hour, 

 (c) Attaching lightning-rods 1 man, 4 rods 

 per hour. 



(d) Guying and anchoring 2 men, 2 an- 



chors per day. 



7 Station Installation 



(a) Best 1 man, 3 hours (indoor). 

 2 men, 2 hours (outdoor). 

 (&) Worst 1 man, 5 hours (indoor). 

 2 men, 4 hours (outdoor).
