I have re-charted the design and worked it in the extended double crochet stitch. The charts are easy to read and include both graph and virtual stitch. This chart is only 25 squares by 31 squares, is quickly accomplished and can be used in a variety of ways Works published before 1923 are in the public domain, the copyright has expired on the original design. However, I retain the copyright on my re-worked charts and graphs.
I used the extended double crochet stitch to give a more square piece, but feel free to use the normal double crochet or even the treble crochet to work your piece.
