'Your remarks on the heating by hot water for your 

 work are, according to my experience, quite to the 

 purpose. I remember of once listening to a lecture on 

 heating by hot water given at Chiswick by the late 

 Dr. Arnot, wherein he stated that the boilers on the 

 saddle principle were perhaps the safest and most efficient 

 of any, and the easiest understood. The great thing in 

 hot - water . heating, he said, was always to lay down 

 plenty of piping, so that the boilers were never worked 

 too hard to keep up the desired temperature. All the 

 saddle boilers that you laid down (17 or 18 years ago) 

 are as sound as ever, and working every day in high 

 and low temperature, according to the houses, stove, 

 or temperature, the only alterations or faults in them 

 being the mending of a few rivets in the plates; all 

 the pipes have been remarkably well placed and soundly 

 stopped. You state the truth in relation to using the 

 best iron for the plates of saddle boilers, such as the 

 Low Moor, and thereby I believe their lasting qualities 

 are proportionably increased. The late Mr. Ingram, 

 when gardener to Her Majesty at Frogmore, used saddle 

 boilers of the best iron for heating the fine new range 

 of houses there, and I believe they are still in use, 

 or were lately. — I am, dear sir, very truly yours, 



' Wm. Tillery.' 



I considered a few remarks on heating might benefit 



some of the readers of this book.
