To place under the conditions of a bond; to mortgage; to
secure the payment of the duties on (goods or merchandise) by giving a
bond.

A writing under seal, by which a person binds himself, his
heirs, executors, and administrators, to pay a certain sum on or before
a future day appointed. This is a single bond. But usually a condition
is added, that, if the obligor shall do a certain act, appear at a
certain place, conform to certain rules, faithfully perform certain
duties, or pay a certain sum of money, on or before a time specified,
the obligation shall be void; otherwise it shall remain in full force.
If the condition is not performed, the bond becomes forfeited, and the
obligor and his heirs are liable to the payment of the whole sum.

The union or tie of the several stones or bricks forming a
wall. The bricks may be arranged for this purpose in several different
ways, as in English or block bond (Fig. 1), where one course consists
of bricks with their ends toward the face of the wall, called headers,
and the next course of bricks with their lengths parallel to the face
of the wall, called stretchers; Flemish bond (Fig.2), where each course
consists of headers and stretchers alternately, so laid as always to
break joints; Cross bond, which differs from the English by the change
of the second stretcher line so that its joints come in the middle of
the first, and the same position of stretchers comes back every fifth
line; Combined cross and English bond, where the inner part of the wall
is laid in the one method, the outer in the other.
