The acciirate sampling of stream bottom gravel to detennine its con- 

 tent of fine material is a difficult task. The sampling tools used 

 to date are not entirely'- satisfactory. Large rocks, presence of bed- 

 rock, and swift, deep water make it difficult to obtain samples in 

 many desired locations. A considerable amoimt of the fine material 

 in the sample is lost, as it is washed out in the water trapped in 

 the sample. Because of these undesirable features a new study 

 (buried cans of washed gravel) was initiated during the 1955 season 

 which it is hoped will provide some realistic values of the build-up 

 of sediment in the upper layers of the stream bottom.
