SEASON OF 1933 
In 1933 complete counts were made on shells planted in the same periodic manner 
in dikes 5 and S, and in addition two other adjacent bays were included (see tables 23 
and 24). The three bays are treated together because of the similarity of the setting 
periods. Little Skookum (Skookum Inlet) is a small bay which branches off from 
Oyster Bay about half way between the mouth and the upper end, and well down from 
most of the oyster grounds (see chart, fig. 4). The mouth of Oakland Bay is very 
near to that of Oyster Bay and it would therefore not seem improbable that the water 
entering the two bodies of water is almost identical. As a result of pollution of the 
water in this region by waste liquor from a pulp mill several years before, the oyster 
beds in Oakland Bay and Little Skookum had been seriously depleted and the supply
