50 ETON NATURE-STUDY 



Every piece of the sod must be treated as described, and well looked 

 through. Continue to work all round the tree, starting from the 

 same distance away from it, and approach it carefully and gradually. 



Some pupae are in the trees themselves, such as those of the 

 Goat- Moths, Clear wings, and many others. These may be found by 

 drawing the hand up and down the bark to find the soft place under 

 which the pupa lies, having worked its way by the hooks on the 

 segments of its body to a spot just under the surface of the bark, 

 to be ready for the emergence of the moth. 



Look over all rubbish collected at the foot of trees, as many good 

 specimens may be found by so doing. 



NOTE 



When leaving a tree, always replace the soil in a neat manner, as it 

 not only makes the place tidy, but it will also leave the ground soft 

 and loose, so that in the future, fresh caterpillars may enter. 



The searcher must always bear in mind that pupae hunting 

 requires a vast amount of trouble and patience, and should the be- 

 ginner find very little to repay him for the first day's labour, he 

 must still continue day after day, until at length he is rewarded for 

 the pains which he has taken.
