b. Frame: Of two horizontal timbers; warp vertical, weft hori- 
zontal. 
1. Front set of warps interwoven with the back set. Obso- 
lete (sec. 475). 
2. Front set of warps interwoven without division (secs. 
465, 466). 
3. Front set of warps interwoven after division into anterior 
and posterior layers: 
i. Each bar distinct from its fellow (secs. 467-472). 
ii. Each bar continuous with its fellow (sees. 473, 474). 
B. Warp and weft continuous: One continuous thread forms a series 
of loops (weft) which progressively locks the warps as they are 
made (sec. 477). 
480. When once the body of the hammock has been completed 
each scale line is inserted in such a manner (fig. 210 A) as to leave 
a number of loose loops (s/) at regular intervals. [For diagram- 
Fie. 210.—Attachment of hammock scale-lines, 
matic purposes only four are shown in the figure.] These loose loops 
of scale line must be very nicely measured and adjusted, for only if 
the center one is the shortest and each successive one on either side 
is made longer than the one before it, so that the outermost is the 
longest, will the hammock hang evenly and comfortably (IT, 290). 
When finally adjusted, the apices of these loose loops of scale line, 
i. e., where they will ultimately rest on the hammock rope, are over- 
east (0c). 
481. The slinging of hammock rope (7) to scale line is done in a 
very simple manner (fig. 210 B) by means of a slip knot. The means 
of attachment of hammock rope to beam, rafter (6), ete., is also 
simplicity itself (C, D, E), so as to allow of a single pull to free it. 
While the proximal end (p) of the rope is dragged on to tighten it 
up, its distal extremity (d@) is pulled on to loosen it.
