Conclusion. 



Though the saving of fuel which will result from the 

 improvements in the forms of chimney fireplaces^ here 

 recommended, will be very considerable, yet I hope to 

 be able to show in a future essay that still greater 

 savings may be made, and more important advantages 

 derived, from the introduction of improvements I shall 

 propose in kitchen fireplaces. 



I hope, likewise, to be able to show in an essay on 

 cottage fireplaces, which I am now preparing for publica- 

 tion, that three quarters^ at least, of the fuel which cot- 

 tagers now consume in cooking their victuals and in 

 warming their dwellings, may with great ease, and with- 

 out any expensive apparatus, be saved.
