Agriculture. Book II. ^RESERVATION AND REPAIR OF ROADS. 607 37:38. J. Farey is of opinion that varying the length of axles, so as to prevent their running in the same track, would be very beneficial. This he particularly stated to the Board of Agriculture, with an example of the tolls over a new road in Derbyshire, which are regulated according to the length of the axle. 3739.

" A man can break an ordinary stick, an inch in diameter, across his knee ; but if he tied ten of these sticks together, he could not break them if he tried ten times, nor if he tried a thousand times ; although, by these thousand efforts, he might have broken a thousand such sticks sepa- rately. A stone might be of such a size and texture that a strong man with a large hammer might break it into pieces at one blow; while a boy with a small hammer, striking it with one tenth part of the force, might strike it a thousand times, applying in the whole one hundred times the power upon it that the man would have done, without producing the same effect.
