. Bulletin - United States National Museum. Science. XoRiii Alaskan Whai inc Umiak of about i8go. Drawn from damaged frame, formerly in a private collection, now destroyed. the Western Alaskan coast and among the islands. The drawing on page 186 represents a large Alaskan tiiniak from King Island. Two boats of this model, hut with modern metal fastenings, are in the Mari- ners" Museum, Newport News, Virginia, but the drawing shows the methods of fastenings used in 1886. The plan is of a burdensome model, such as is used for travel or other heavy cargo work. The boat is 34 feet 2]^ inches over the gunwales, 8 feet ji inch extreme beam, 2 feet jji inches deep and 2 feet 10 inches beam on the bottom over the chines. The construction follows the general plan of the small umiak just described, except that another method of fitting the floor timbers to the chines is employed. Due to the size and use of the umiak, two side battens are employed with a single riser. The thwarts are not notched over the frames, but instead fall between them. As diagonal thong braces from gunwale to keelson would be ineffective in this situation, two sets of wooden braces that resist not only tension but also compression are used to take the thrust off the thw art lashings. These brace-frames are staggered slightly to allow room to fit them at the keelson. The draw- ing, which requires no additional explanation, shows the plan of construction and the important lashings, and the method of fitting oars with thong thole loops. Boats such as these carried a square sail lashed to a yard, the mast being stepped in a block on the keelson. No mast thwart is used; instead stays and shrouds of hide rope supported the mast, a method that made it easy to step or unstep the mast in a seaway. Early umiaks in this area are said to have had mat sails; later ones used sails of skin and drill. Modern umiaks of this class often have rudders hung on iron pintles and gudgeons and the floors fastened to the ke
