16 DEER-STALKING. 



has met with. 'The lenses are so arranged that they 

 can be kept to the eye for ten minutes or a quarter of 

 an hour without in any way dimming the sight or 

 making the eye giddy, and at the end of a long spy 

 with one of these glasses it is as ready and quick to 

 take the foresight of the rifle as if none had been 

 used. When made of aluminium they are apparently 

 expensive, as their price is twenty guineas. This 

 metal is, however, a very difficult one to work in, and 

 up to the present no means of soldering it have been 

 discovered, so consequently all the tubes of each tele- 

 scope have to be cut from the solid piece, and there is 

 a fortune awaiting any one who can discover a solder 

 for this extraordinary light and beautiful metal. The 

 same description of lenses mounted in brass can be had 

 for rather less than half the cost of the aluminium one, 

 and many prefer these, maintaining that the extra 

 weight keeps them steady, and renders them easier to 

 use in a high wind, and that also they are not so liable 

 to get out of order. If you stick to your own glass, 

 carry it yourself, and keep it solely for your own use, 

 an aluminium one will last a life-time. Stalkers and 

 gillies are apt to be a little rough, for they are accus- 

 tomed to brass-mounted glasses, which will stand a lot 

 of hard usage, and can with impunity be torn open in 

 a moment and shut up with a snap bang. 



The writer has never found any difficulty in keeping 

 an aluminium glass in order, or in holding it steady in 

 a wind, and the great difference in weight between the 

 two metals is well worth consideration in a hard day's 

 work.
