A treatise on architecture and building construction . Fig. 77. An objection frequently urged against the appearance ofthe English bond on the face of the wall, is the recurrenceof so many headers, which give the work the appearance ofbeing constructed of so many tile-like blocks. The use ofdiminutive blocks of either brick or stone, in heavy walls,always tends to reduce the apparent strength of the struc-ture, and it loses much of the effect of pcn/iaiiciicc, a veryeffective factor in good design. 21*^, The Flemisli bond is used to overcome, in ameasure, this belittling effect, and is one where only two- r I, -. thirds of the number of headers that occur in English bondare exposed, and each course is composed of a header and 112 MASONRY. § 7 stretcher alternately. The method of laying brick in Flemishbond is shown in Fig. 78. The lap in this case is obtainedby the use of three-quarter bats, both at the external andinternal angles of the wall, as shown at a on the external,and at b on the internal angles. In Flemish bond the closersoccur in the heart of the wall, just as was shown in Englishbond; these are quarter, half, and three-quarter bats, asshown at c. It will be seen by referring to Fig. 78, that owing to theheaders and stretchers being placed on the inner side of thewall immediately opposite those on the outer face, bothfaces will appear exactly alike when thus arranged; the wallis then said to be built in double FleviisJi bond. By carefully examining Fig. 78, it will be seen that onlyone-half of the body of the 4-inch tliickness is bonded tothe adjacent thickness; in other words, the
