Historic Paddle Illustration: D.C. Beard - BoatBuilding and boating (1911)

Archive.org has a free online edition of Boat-building and boating (1911) by Daniel Carter Beard. Chapter VI features bark canoe construction. The images look to be replicas of Adney's famous sketches and are quite detailed. On page 60 is a crude sketch of some paddles with rough dimensions. The only detailed provided  is a brief caption posted below:

Paddles are made of rock maple, and sometimes of birch and even cedar. Bow paddles are usually longer and narrower in the blade than stern paddles (Fig. 101).
