lakes where their feeding habits are markedly different, or to correlate 

 actual abundance of foods in streams with actual consumption by 

 trout. We are doing this as a part of the work of the California Trout 

 Investigations, the data obtained to be applied toward the development 

 of a scientific stocking policy. The real basis of all economic progress 

 is a detailed knowledge of life histories and habits. Applied to the 

 conservation of trout, the more facts that can be discovered concern- 

 ing their life histories and habits, the better fitted we shall become to 

 develop intelligent methods of stream management.
