Il8 CONSTRUCTION AND MANAGEMENT OF SMALL GASWORKS 



It is a mistake to endeavour to utilize old pattern and 

 possibly badly worn lanterns for the incandescent burner. 

 If this burner is adopted at all, it should be done on 

 sound and substantial lines, so as to ensure complete 

 success; and decrepit lanterns and accessories will not only 

 be a bad advertisement, but will greatly increase the 

 trouble and expense of maintenance. If a well-designed 

 modern make of lantern is already provided, and is in a 

 sufficiently good state of repair to warrant the outlay, there 

 is no difficulty in converting it, at a small expense. But an 

 old type, with frames an inch wide, is not worth retaining. 

 One frequently finds the lanterns supported in loose frames 

 or cradles, instead of being firmly secured to the top of the 

 column by the medium of a frog. The arrangement saves 

 trouble when taking the lanterns into store for the summer, 

 but has nothing else in its favour, and it will not do for the 

 incandescent burner. Not only must the lantern be rigidly 

 secured, but there must be a reasonably substantial and 

 sufficiently stiff or rigid support to carry it. Light rolled 

 tube pillars, or slightly made brackets, are dear at any 

 price, for modern lighting. 



When contemplating buying new lanterns, it is well to 

 remember that there is now no reason for adhering to the 

 old fashioned four-post bedstead type of lantern. Hemi- 

 spherical or egg-shaped globes diffuse the light much better, 

 cast no shadows, and cost less for maintenance. Various 

 forms of adapters, for enabling lamps of this pattern to be 

 fixed to ordinary lamp pillars, are on the market.
