29^ ADVANTAGES OF GAS LIGHTS. 



burn in my small stoves in the shops as coal ; so that I do 

 not overrate this, when I say £2 10s. for it. The expense 

 ©f putting up my apparatus was about ,£50 ; but not know- 

 ing the cheapest and readiest methods to go about it, it cost 

 me more than it ought by £\5. I will say £A0, for which 

 in my statement at the conclusion I shall allow interest. 



Advantageous If erected on a smaller scale, the saving to the manufac- 

 on a still smal- , . ,.1 1 i- i , 1 



ler scale. turer is equally as great ; tor the poor man, who lights only 



six candles, or uses one lamp, if the apparatus is put up 

 in the cheapest way, will find it cost him only £\0 or £19. ; 

 which he will nearly if not quite save the first year. And if 

 the pipes are made of old gun barrels, as mine are, and 

 once a year, or once in two years, are coated over with the 

 tar to keep them from rusting, they will last half a cen- 

 tury. The burst or waste barrels, that used to be sold for 

 old iron, would then produce a better price to the gun 

 makers; and the pipes would be better and more durable, 

 than if made of more slight materials. 

 The profit un- You see I have reckoned the five shillings per week for 

 derrated. ^^ j^jan the whole year, as also the same expense for coal 



for the whole year, of course that is reckoning more than I 

 ought by nearly a fourth ; but where soldering with the 

 blowpipe is necessary, gas will be wanting, although in 

 smaller quantities, in summer as well as winter, and I am 

 desirous of overrating the expense, rather than otherwise, for 

 fear of any accident in a retort being melted, &c. 



Now I do think, the more generally this is made known, 

 that the industrious tradesman may derive from it the benefit 

 he ought, the benefit nature has so bountifully supplied this 

 nation with, the better : especially when candles and oil are 

 risen to so great a price, which is a very great drawback on 

 his profits and industry. 



If you can extract any thing from the above imperfect de- 

 scription, that may be of any use, and put it into a shape, so 

 as to make it worth inserting in your Journal, I should be 

 glad. You see what my object is : to show to the middling 

 man as well as the great one, that a considerable saving and 

 advantage may be derived from the use of gas in his manu- 

 factory. I have said nothing about the greater safety there 

 is in its use than in that of candles ; there being no dauger
