awake certain slugs, and some of their allies which possess shells, for 

 instance. Insects too are by no means all dead. The question of 

 birds and berries has already been mentioned, and it would repay 



consideration. Some interest may 

 also be gained from tracing the 

 footprints of birds and mammals 

 made in snow, and then trying to 

 tell what creatures made them. 



ROCKS AND FOSSILS 



tranrvK^H After the work of frost in mould- 



ing the face of the earth has been 

 watched, the sections through the 

 ground which expose various rocks 

 in the neighbourhood may be ex- 

 amined, and the remains of animals 

 and plants which they contain 

 may be collected. The exercise 

 necessary to obtain these is often 

 quite sufficient to keep the fossil 

 hunter as warm as he cares to 

 be. Quarries and railway cuttings, 

 the banks of streams, and sea-cliffs are good hunting grounds for 

 fossils. In the naming of these, if the work proceeds upon definite 

 and scientific lines, help should be obtained from some local geologist.
