Publisher's Synopsis

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1847 Excerpt: ...which established the weighing system, was passed in October, 1831. This salutary change from a system (at one period) fraught with endless frauds, and anomalous inconsistencies, to one yielding results of mathematical accuracy, may be said to have sprung out of the proceedings instituted by me, when a very near approximation to a truly defined measure (and weight) was effected in the substition of the stroke for the heaped tops, which being analogous to the treatment of grain, cannot be far from the truth, if properly attended to. This change from weight to measure, was followed by a corresponding alteration in the mode of ascertaining the pitmen's earnings weight being also adopted in the collieries instead of the old corf, or basket, measure--a change attended with beneficial effects, as thereby the interminable disputes (on that head) between the coal owners and their workmen were got rid of. EXTRACTS FROM ACTS OF PARLIAMENT RELATING TO THE COAL TRADE. 6th And 7th, William The 3rd, Cap. 10. Section 1.--Refers to the 9th of Henry the 5th and the 30th of Charles the 2nd, which have (it is stated) proved insufficient to prevent frauds. (It is worthy of being remarked, however, that the Act of Charles, just referred to, sec 2, cap. 8, fixes the chaldron at 21 bolls heaped measure, each boll to contain 22 gallons and 1 pottle.) Section 2.--Commissioners from time to time to be appointed for admeasuring and marking all keels, pan keels, pan boats, and other boats, and wains and carts used, or to be used, for the carrying of coals, allowing 53 cwt. to every chaldvon.

Why are there so many typos in my paperback? The book descriptions we ask booksellers to display prominently warn that our books contain numerous typos. Most book sellers display our descriptions. But if they don't, unfortunately, there's nothing we can do. We created your book using OCR software that includes an automated spell check. Our OCR software is 99 percent accurate if the book is in good condition. However, with up to 6,000 characters per page, even one percent can be an annoying number of typos. We carefully proof read the books we expect to sell enough copies to cover the cost of proof reading. But that could add more than a thousand dollars to the cover price of the rest. And nobody wants to pay that. If you need to see the original text, you can download a copy for free. Why is the index and table of contents in my paperback missing (or not working)? The book descriptions we ask booksellers to display prominently warn that our books are not indexed. After we re-typeset and designed your book, the page numbers change so the old index and table of contents no longer work. Therefore, we usually remove them. Since many of our books only sell a couple of copies, manually creating a new index and table of contents could add more than a hundred dollars to the cover price. And nobody wants to pay that. If you need to see the original index, you can download a copy for free. Why are illustrations missing from my paperback? The book descriptions we ask booksellers to display prominently warn that our books are not illustrated. We typeset our classics paperbacks using OCR software. Therefore, they don't have illustrations. We would really like to manually scan and add the illustrations. But many of our books only sell a couple of copies so that could add hundreds of dollars to the cover price. And nobody wants to pay that. If you would like to see the original illustrations, however, you can download a scanned copy of the original book for free.Why is text missing from my paperback? The book descriptions we ask booksellers to display prominently warn that our books may be missing text. Unfortunately, all or part of a page is occasionally missing from our copy of a book. Or the paper may be so discolored from age that you can no longer read the type. We would really like to track down and buy multiple copies of those books to compare and manually proof read and correct any missing text. But many of our books only sell a couple of copies so that could add hundreds of dollars to the cover price. And nobody wants to pay that. If you would like to read the original scanned book, you can download a copy for free.
