open to the public ; the expense of adapting it to each boiler is only 

 from 21. to 3/. ; and Mr. Billingsley's charges for directing the same 

 I believe are very moderate. We may hope, therefore, shortly to see 

 the chimney of an engine producing no more smoke than is ordinarily 

 produced from the chimneys of common dwelling-houses, and look 

 forward to a total change in the appearance of the manufacturing 

 districts, as well as to an incalculable improvement in the health, 

 cleanliness, and comfort of the inhabitants. The amateur gardener, 

 the cottager, the landscape gardener, the horticulturist, and agricul- 

 turist will then pursue their various avocations with confidence and 

 pleasure when their great and common, enemy is annihilated. It 

 would be well if this system could be applied to fires appropriated to 

 horticultural purposes, for, besides ridding the garden of a perpetual 

 nuisance, it would effect a considerable saving of fuel, as well as of 

 trouble in cleaning out the flues; and the flues, being less encum- 

 bered with soot, would give out heat more equally and readily. It 

 might be done, no doubt ; but it would require considerable alter- 

 ations, owing to the difference there exists in the formation of a 

 furnace for an engine-chimney and that commonly used for garden 

 purposes, and to the different modes in the application of fuel. 

 However, as I have to superintend the erection of some hothouses for 

 a gentleman, I shall endeavour to introduce Mr. Billingsley's system, 

 with such alterations as I think necessary ; and should my efforts he 

 successful, I will announce them without loss of time.
