This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ...the openings run vertically, and in the course above an 8-in. length of the 8x16-in. section is used in the same manner as at the corners. The blocks are generally made, as shown in sketch, with I-in. walls, and are usually vitrified and glazed, being similar in appearance to sewer pipe, but a hard-burned red block is very sightly and very durable if properly made. As to exact dimensions, it may be stated that the thickness of the mortar joint is the first item to be considered, and granting that % in. is sufficient for strength and gives better appearance than a thicker joint, the 8x8-in. stretcher blocks should be cut 16% in. long, and the corner blocks should be 8 x 16% in. in cross-sections, cut 8 in. long. The sketch styled "Flemish" shows a method of using hollow block which has a great many advantages, and at the same time objectionable features, which should not be overlooked. It makes a bond after the fashion of the old Flemish, has quite an attractive appearance, and gives each block a dead air space in itself, avoiding the possibility of air circulation through imperfect joints; but on account of the large percentage of small blocks it requires more time and mortar to lay up the wall, and possibly makes the structure cost more than is warranted by the advantages gained. However, it is a very good bond and makes an 8-in. wall cheaper and better than brick; not so much cheaper as some of the bonds shown in the other sketches, but better than any of them. To make the block for this system only one die is required, and the ware has to be cut only in two lengths, the corner blocks and the short stretchers being made to a length equal to the thickness of the long stretchers, so that they may be laid with the openings...
