In the 19th century travel by roads was slow and treacherous and railroads had not yet been established. Canal travel, for passengers and cargo, was a dependable means of transportation; canal boats helped to link Pennsylvania's major cities and its rural communities.
Many types of wood were used in building canal boats. White oak is a dense, strong and durable hardwood and was especially good for the skeleton of the boat: its keel, stern posts and frame. Oak also was used for planking. Yellow pine is a dense, pitchy, and rot-resistant softwood that was used for planking, deck beams and ceiling. White pine was used for decking because it shrinks and swells very little; therefore, the seams would remain tight and water resistant.
The frames of the boat are like the ribs of our bodies. They join the backbone, or keel, and determine the shape of the body, or hull, of the ship. Adzes, axes and saws were used to rough cut the frames. Large clamps were used to hold the pieces of timber in place until they were nailed together. The sides of the boat were planked after the stern post and frames were in place. Long, narrow boards were cut to line the frames both inside and outside the boat. These planks formed the boat's "skin." Through careful calculations, boat builders cut the planks almost exactly to shape then used steam to fit

them snugly against the curves of the hull. Hard wooden pegs, like nails made from a tree, were driven through drill holes to fasten the planking to the boat frame. Planes were then used to smooth the planking and decking.
[Right inset text reads]
Planks alone did not keep the water out. After the planking was in place, caulking could begin. The process began with men jamming the fibrous substance "hemp" into the spaces between the planks. Tools needed for this task ranged from mallets to various wedge-like devices called irons used to push the tarred hemp called "oakum" into place. Once the seams were packed with hemp, another man would use a brush to swab hot molten pitch over them to make the boat watertight. A fresh coat of paint was then applied to the caulked boat.
