Connected with this dam, similar sticks are placed up stream so as to form little pens. The salmon leaps over the dam, falling into the pen, and is readily caught by the Indian who is on the watch sitting on a mat placed on a slab on the pen. On the sand spits nets have been suspended from tall poles for the purpose of catching wild gadis and geese at the time of their annual flights. They fly against them in the night and kill themselves.
Fortunately I had some of the venison from a buck the doctor had killed. The clams are accessible to us as well as to the Indians, besides which among our regular supplies we have bread, coffee and sugar. The Indians themselves live mainly on salmon and clams. They have a few potato patches, and I presume they also kill some game, but although it is quite abundant, it is very difficult to get on account of the timber.
