PHOTOGRAPHY OF MAMMALS AXD BIRDS.

employed, one hole had been cut through an end 

 sufficiently large to take the lens mount, but not the 

 shutter attached to it ; further, there was no supple- 

 mentary pane of glass. The box had been about halt 

 filled with mould, and the corners left in their ordinary 

 square condition. The rat commenced by rushing 

 with loud squeals from corner to corner, raising a cloud 

 of dust in every 

 direction. The 

 sun happened to 

 be shining on 

 the glass cover, - ^B 

 with the result 

 that the inner 

 side of it soon m 

 had the appear- 

 ance of having 

 been rubbed in 

 mud. This 

 meant that the 

 actinic power of 

 the light inside 

 was about halved. 

 Finally, our friend commenced to burrow under the; lens. 

 This position, of course, was hopeless. The glasses 

 forming the cover were carefully slid along so as to 

 leave room to insert a piece of wire between the end ot 

 the glass and the end of the box. The result of the 

 application of the wire to the rat was somewhat 

 unexpected. With one bound he had leapt on to the 



Hedgehog.
