Figure 1 . — A typical oar-propelled seine boat generally used during the early development of the herring 
fishery. A large steam or motor vessel towed or carried on davits two of these boats with half of the seine 
in each boat. When a school of fish was discovered the two seine boats were rowed around its opposite 
sides and the seine pursed by hand. This method was last used by the Big Port Walter plant in 1926.

with a 17-foot beam, 46 tons gross and 31 tons net, built in Tacoma in 1927, and equipped with a 90-horse- 
power Diesel engine. Taken at Big Port Walter in June, 1929
