Second Letter on the Advantages of Coal Gas Lights, By 

 Mr. B. Cook. 



To Mr. NICHOLSON. 

 SIR, 



AN my last letter I promised you a few plain drawings, but On the advarw 

 I have been out of Town nearly three months since I wrote f?S«* of 8 as 

 to you, which has hindered me from sending them. I am 

 desirous, however, if possible, to hand you the few following ' 

 remarks, in addition to my last letter, in time for your Jour- 

 nal. 



First, with respect to oil and cotton, the man who does Where no sol- 

 not use these articles, may unthinkingly strike that out of a ^" r g| 1S re " 

 the statement, and then there appears but little or no ad- 

 vantage from the adoption of the use of the gas lights. 

 But he must not do this: for, if he do not use these arti- 

 cles, a large portion of the expense in the execution of the 

 apparatus is saved, and one lamp will consume as much gas 

 as nearly twelve lights, or candles. If this is duly consi- 

 dered, the saving is the same, or nearly so; for less gas will 

 be wanting to be made, less coal consumed, and the man or 

 boy, that makes the gas, will perhaps be required to make 

 it only two or three times a week, instead of every day, 

 which will be the case, if the gasometer is small and lamps 

 used. Instead therefore of employing a man a part of his 

 time at five shillings per week, a boy will be employed to 

 do it at perhaps two shillings per week or less. Indeed in 

 most manufactories a boy or an old man is kept to job, or 

 go on errands; and he will be able to do this and all his 

 other jobs besides; so that in most manufactories this man, 

 which forms a very great portion of the expense, may be 

 entirely struck out. Besides, the industrious man, who 

 works in his own shop, may do it himself, as the trouble is 

 little, only putting a fire under the retort, and filling there- 

 tort with coal ; when it will require no farther attention, ex- 

 cept to see now and then that the fire is kept up.
