Stoke-Nervington, March 18 th, 1834. 
Sir,—H aving only used the Apparatus invented by Mr. Witty 
Tor a few days since you put up the same, yet I cannot withhold my 
approval of it; as far as I can observe it quite deseryes all the enco¬ 
miums which has been bestowed on it, as the purpose to which we 
have applied it, viz. to heat a Steam-Boiler; the flue of which takes 
a horizontal direction of 150 feet to warm a pipe, which 1 consider 
has a deadening effect to the draft, after which it takes a perpendicu¬ 
lar direction in a chimney. It appears to answer every purpose an¬ 
ticipated, we have as little smoke as it is possible to expect; the fire 
is more effective under the boiler, and it consumes less fuel. I in¬ 
tend, after a month’s trial, to write to Mr. Chanter on the sul ject, 
when I may be better prepared to state facts : in the meantime, 
should you see him, you can explain to him that we are quite pleas¬ 
ed with it so far. I write thus much to you, thinking, perhaps, both 
you and Mr. Chanter may naturally be anxious to know the result. 
We remain. Sir, 
Your Obedient Servants, 
Mr. Walton. WM. ADAMSON & SON. 
University Gardens, Nov. 28th, 1832. 
Sir,’—I t is upwards of twelve months since the erection of our 
Gas-Furnace; and since that time, both Mr. Fairburn and myself 
are perfectly satisfied that it A has all the advantages you had led us to 
expect. The fuel we burn is of the very worst description,—so bad 
that when a gentleman (the Rev. Mr. Baker) of Nuneham Court¬ 
ney, who called to see our apparatus in operation a short time since, 
appeared to doubt the possibility of consuming such refuse, until he 
saw the carbonizing plate charged with it, which was producing a 
very high temperature in the hothouse. I am glad to hear you have 
fixed one to his hothouse, which I am sure will give great satisfac¬ 
tion, as it may be managed with half the trouble and half the con¬ 
sumption of coals. I think the most appropriate name for it would 
be “the Garden’s Friend,” as we are never required to attend the 
fire from seven or eight in the evening until the same hour the next 
morning. During the whole of last winter the fire was not out for 
weeks together. Mr. Fairburn wishes you to call at the Gardens, 
and take dimensions for applying one to each of our pine-pits and 
greenhouse. 
I am, Sir, your very humble Servant, 
THOMAS COLLFiY, 
Gardener to Mr. Fairburn.
