RELIGION 57 The religious concepts of the Bella Coola are not limited to explanations of strange apparitions, nor to knowledge of a wide range of supernatural beings, anthropomorphic or zoo- morphic. Many in whom they believe are invisible and intan- gible, though none the less potent. Almost every incident of life is attributed to the help or hindrance of a supernatural agency. If a fisherman constructs a salmon-weir, with a considerable amount of work, the Bella Coola ascribe his suc- cess to the assistance of some supernatural being or super- normal power; mere labour would never have sufficed. Ifa man has phenomenal success in hunting, it is because the supernatural has helped him in some way. It is not necessary that an anthropomorphic being should appear; they seldom do, but none deny that in some form or another supernatural ones have aided the enterprise. This attitude is clearly evident in Bella Coola beliefs concerning the construction of canoes. Many professions depend upon prerogatives without which a person cannot hope to succeed. This is not true of canoe-makers, although it is a great advantage to one of them if Yuldtimut, the Master Carpenter, appeared to his ancestors in the beginning of time. Even without this in many cases a man can succeed in making a canoe if he is aided by a supernatural teacher, or Model Maker. No one knows much about this being, nor even whether there is more than one of them, but it is through his kindly intervention that a man is able to complete his complicated task. If carpenters who have left a half-finished canoe in the woods, hear adze beats, as they are returning to it, they remain away from the spot, knowing that their work is being done with superhuman efficiency by a supernatural artisan. Under such circumstances even a solitary man can construct one of the large, ocean-going canoes. About 1880 an expert carpenter, named Yefx/in, was making stated definitely that his mother had told him Mackenzie came down the Dean River when her uncle was a young man. As if to confirm this statement he added the inconsequential detail that Mackenzie, in dire straits for food, killed and ate a dog, and that he was given a marmot-skin blanket.
