A NATURE CAMERA 17 



I need scarcely add that if a camera of longer extension is required, it can 

 be made on the same lines but instead of a " cramp " costing a penny, a 

 proper " rack and pinion " set of fittings would be required, or what is known 

 as a " focus screw," costing about 53. 



One other advantage of the camera, made as I have described it, is that it 

 is fairly substantial and solid, and will stand a good deal of hard wear. 



I do not deal with the question of stands, or the other adjuncts of a photog- 

 rapher's outfit, which belong more properly to a book on photography pure 

 and simple. Nor do I think it necessary here to treat of the subject of bird 

 photography, with its devices for concealing or disguising the camera. 



The special object of the camera designed above is rather the photography 

 of " still life " : a hobby to which there is no end, and one which, if adopted, 

 will prove of the greatest value to the Nature student I may add, of great 

 interest to others besides himself, if he is able to turn his pictures into lantern 

 slides. 



Those of my readers who are interested in the microscope and desire to 

 take photographs of mounted objects can use this same camera, using, instead 

 of the telescope objective, the other end of the instrument. Either the whole 

 of that portion DE (in the diagram of the telescope) can be used whole, or 

 the little objective which is at D, or half of that objective. No cap is 

 required for making the exposures, but a piece of black cardboard is inter- 

 posed between the lens and the object, which is removed when the plate is 

 ready for exposure. 



For further details on this most fascinating branch of Nature study I must 

 refer readers to The Young People's Microscope Book.
