No yardage given, no hook size, gauge given was as follows:
“White crochet-cotton, No. 50, was used for
the model; coarser thread will result in a larger bonnet,
using the same directions. The one illustrated is about
fourteen inches face measurement, or from one corner of
front to the other.”

The pattern appears to be written with UK crochet terms, despite being produced in Maine. Read the explanation of stitches carefully.

Roll-stitch. This stitch. revived as are so many of
the “new” things, was formerly called bullion-stitch, It
consists simply of a coil of “overs” through which the
thread is drawn. Working on any foundation. and
having a stitch on the needle, wind thread around the
latter smoothly ten times, or as many times as called for by
your directions-such details are always given; insert
hook in work, take up thread and draw through, again
and draw carefully through the coil on the needle, again
and draw through the remaining stitch. A slender
needle, tapering to the hook, is better for the purpose
than a straight one, and its passage through the coil or
roll is facilitated if the latter be held firmly between the
thumb and finger of the left hand as the hook is worked
through by the right, The length of the roll-stitch is
determined by the number of “overs” used. Abbreviation is
roll st.
