In describing the various manipulations in binding a book, it has frequently been necessary to refer to the presses, machines, and tools requisite for their proper execution. Skilled and proficient as the binder may be, and however good the material he may have for use, unless he is aided by good presses and well-executed tools, his work will not present some of those important qualities of good binding laid down in previous parts of this treatise, viz. solidity in the forwarding, and true proportion in the finishing. In fitting up an office, it becomes therefore necessary for the proper execution of the work, and the consequent reputation of the binder, that he provide himself with machinery, &c. of the best manufacture only. True it is, that the cost may be greater, but assuredly it will soon be amply repaid by the increased effect produced, and the consequent satisfaction which superior workmanship will always give to the possessor of a library. But, with judgment, a greater cost need not be incurred, for, as has been before observed, the binder may be enabled to purchase the necessary and most approved articles for his establishment for a smaller sum than, without calculation and reflection, he would expend in procuring those of an inferior description.
