What reading level is A Brief Practical Treatise On the Construction And Management of Plank Roads book?
To quickly assess the difficulty of the text, read a short excerpt:
Geddes of Syracuse, informed me, that the result of various experiments made on different two-horse ploughs of approved construction, at an agricultural fair in that neighborhood, showed a traction, under ordinary circum- stances, varying from 300 to 500 Ibs. Nor is the direc- tion of force to draw a plough the most favorable for a horse ; the line of direction should be level with his breast. Desaguliers says a horse can draw 240 Ibs. For six hours a day. And it is said, that a horse of extrao...rdi- nary power has, for a momentary exertion, drawn as much as 800 Ibs. The power of draught decreases sensibly as the velo- city increases. Most writers set down the power of a horse going five miles an hour at cbout half the power of 76 the same horse going 2 miles only; and estimate, that the power is reduced to one quarter, if the velocity be increas- ed to 8 miles an hour. Again, on steep grades, horse power rapidly diminishes. If continued exertion for 8 or 10 hours a day be demanded of a horse, the usual estimate is, that up an ascent of 1 in 7 he can carry his own weight only.
