This statement, reduced as much as practicible to a tabular form, you will cause to be printed, as the information to be given to persons upon which to make their proposals, and it will be embodied in or attached to the articles of agreement as a specification of the work to be done.
As you will find it convenient to have the prepared metal piled in uniform masses, admitting of the application of a gauge to ascertain whether or not the required quantity is in the pile, you will cause such gauges to be made with slopes of 45 degrees and in no instance permit a measurement of stone to be made without having previously verified the dimensions of the gauge. The necessity for this you will perceive by reflecting that the end of the gauge may be cut off and the angles altered to make a material difference in the quantity, without being perceptible to the eye.
The following are some of the frauds heretofore practiced, and now enumerated that you may look cautiously to their not being practiced upon your section of the road: i 1st. Diminishing the size and altering the angle of the gauge.
2d. Loosening the pile of metal just before the measurement, to increase its bulk.
3d. Concealing or covering up in the piles of metal large masses of stone or other matter.
4th. Breaking stone of a softer or otherwise inferior quality than the sample agreed upon.
5th. Breaking the metal to a larger size than that agreed upon.
6th. Removing the prepared metal from one point to another after it has been measured.
7th. Taking metal from the face of the road, of the first or second stratum, to make it appear the desired quantity has been broken to fill the gauge.
