" The following are some of the advantages which this new boiler possesses : — 

 1. It requires no brickwork in setting ; this is a very important consideration, 

 for should the necessity at any time arise to repair the boiler, much labour and 

 considerable inconvenience are avoided, besides which there is the saving in bricks 

 and labour in the first instance. 2. It does not require a bulky chimney-stack, 

 a stout sheet-iron chimney answering every purpose. 3. It is complete in itself, 

 having perfect means of regulation. 4. It takes up little space, and can be fixed 

 in places inaccessible to other boilers. 



5. It consumes its smoke, and is econo- ||'- f rffi CK:MNi: '' 



mical in respect to fuel ; this last is a JMyJr 



very great advantage, for the expense of 

 fuel, in many parts of the country, 

 proves a serious hindrance to those who 

 would gladly gratify their taste for hor- 

 ticulture. 6. In case of an accident, it 

 can be taken away, and another put in 

 its place in the short space of two hours, 

 during which little or no harm could 

 happen, even during frosty weather. 



" Mr. Green has, I believe, conferred 

 a great boon on amateurs and persons 

 of limited means, by producing a boiler 

 capable of heating a large or small space, 

 with a very small quantity of fuel ; and 

 when once the pipes are warm — which, 

 according to Mr. Eyles' experience, will 

 be in the course of half an hour after 

 the fire is lighted — very little attention 

 is required to keep all right. 



" The boiler at Kensington is 4ft. 8in. 

 high, and 2ft. 4in. in diameter, and has 

 upwards of 100ft. of four-inch pipe 

 attached to it. The amount of coke 

 consumed in twelve weeks, since the 

 15th of October, is six chaldrons, which, at lis. 6d. per chaldron, amounts 

 to £3 9s. Od. As it has been found necessary to keep one of the furnace 

 doors almost continually open, to check its action, it is fair to assume that 

 the boiler would, if required, do double the work here allotted to it. Mr. 

 Eyles reports that he cannot tell what its capabilities really are, his difficulty 

 having been to keep the heat sufficiently low. The boiler is made of the best 

 wrought iron, capable of bearing a pressure of 401b. to the square inch, and the 

 tubes, which are placed crossways inside the boiler and immediately over the fire,
