tion, and have no doubt it is more 

 pleasant, and perhaps less trying, to 

 the sight. 



A still cheaper lantern is the ' W. I. 

 A. improved ' (fig. 35) , introduced by 

 the Scovill Manufacturing Company. 

 The source of light is a candle, and 

 it gives sufficient light for develop- 

 ing, but the reader is strongly ad- 

 vised not to be content with such a 

 small lantern if a larger one can be 

 aftbrded. Abundance of non-actinic 

 light in the dark room is very desira- 

 ble, as it obviates the strain upon the 

 eyes, and enables work to be done 

 with far more comfort. 



In passing we may mention the 

 very excellent device of Mr. Walms- 

 ley known as the pocket lantern, 

 price 90 cents, which is very useful 

 in travelling for changing plates, and 

 even for developing. Another port- 

 able lantern is Scovill's ' W. I. A.' 

 lantern, which likewise stows away 

 very well. This, however, is not 

 to be highly recommended, since if 

 the lamp is not very carefully regu- 

 lated, it produces more smoke for its 

 size than any other apparatus under 

 the sun.

shown in fig. 36, is convenient, but 

 by no means essential. The same 

 object can be sat-

 plates, by driving 

 longtacks or nails 

 in an upright 

 board in such a 

 manner that the

 Dark Room.- 

 This should not 

 be too small for 

 comfort, and it 

 should be fitted up 

 for convenience 

 of working. 

 Everything should be kept in good 

 order within it, to avoid mistakes 

 in the use of chemicals in the fee- 

 ble light. Should there be an out- 

 side window it may be glazed with 

 orange or ruby glass and an abun- 

 dance of non-actinic light admitted
