This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1904 edition. Excerpt: ...only necessary to multiply the earth load as given there by /10 (or 60 per cent.) to find the equivalent load of solid rock. Another way to estimate loads is to use the ton of 2,000 Ibs. as the unit. Solid rock seldom weighs more than 2.2 tons per cu. yd. Over poor earth roads, with occasional steep pitches, a load of 1 ton is practically all that an ordinary team should be counted upon to haul, or less than l/2 cu. yd. of solid rock. If the road is hard and level, a team will haul 1 cu. yd. of solid rock; or one horse will haul l/2 cu. yd. in a cart. If the road is a good macadam all the way, with no grades over 4 per cent., and no pulls through soft earth, a good team can haul about 12 cu. yds. of solid rock, but these conditions are exceptional. In ordinary city and village work, and on level hauls over hard earth roads, assume 1 cu. yd. of solid rock as a load for two horses. A team travels 220 ft. per min., or 22 miles an hour, at a walk over ordinary earth roads, a little faster over good pavements and a little slower over soft roads, the variations from this average of 22 miles an hour being seldom more than 20 per cent., making it about 2 miles an hour over poor roads to 3 miles an hour over the best maeadamized roads. It is perfectly safe to say that a team can walk steadily for 8 hrs., averaging the speeds above given, going loaded and returning empty; so if the shift is 10 hrs. long, and not over 2 hrs. are lost in loading and dumping, the team has 8 hrs. to travel, in which time it will cover 16 miles over poor earth roads, 24 miles over good macadamized roads and 20 miles over ordinary earth roads. If the hauls are short it may happen that so much time is lost in loading and dumping that the team has considerably less than 8...
