This work was done between the 10th and 24th of De- 

 cember, in very frosty weather; and the pipe was covered 

 Vith earth before the entl of t}>at month. It is about two 

 or three feet beneath the surface, in a loose, sandy soil; and 

 xvas kept constantly full of water, without any appearance 

 o^ leaking. 



The water was so much discoloured by the iron for a The water »t 

 week or two, and on standing deposited so much scdi'meht, ^^^' discolour- 

 that it could not be used. To remedy this the same mason but this reme- 

 r^^commenrled to put some unslacked lime into the u p- " ■ ^^^ ^*®^' 

 per reservoir, or head of water, and open all the cocks be- 

 low to give it a quick run ; which he said would leave a 

 coat of- lime round the inside of the pipe, so as to prevent 

 the rust from coming off. This wasi done, and for a few 

 days after the water tasted very much of the lime; but the 

 taste soon went off, and the water, which is very soft, was 

 as gdod after it had passed through the pipe as at its 

 source. 



In the following autumn the same gentleman soperin- Another water 



tended the laying down of 36o feet of similar iron pipe, with.''^^'^^"'^ ^, ^

a fall between 20 and 30 feet, the joints of which were se-. stream soon 

 cured in the same way. The supply of water here was. s,o ^^^^"^^ itself, 

 copious, that it was obliged to be kept running all night 

 and great part of the day. This soon cleared the pipe from,- 

 rust, so that after a few days the water came tlirough colour- 

 less, and consequently no lime was used. 



In the summer of 1808, or 1809, two more pipes were Two more iaid 

 laid down in the neighbourhood in a similar manner, ex- ^^^'^• 

 tending together between tw© and three thousand feet; and 

 with equal success. 



These were all perfectly sound and secure in the month pC All contUmc

 sion to put a new leaden pipe in his yard from the iron one, 

 found the latter, as far as it was examined, apparently as 

 good as when laid down, and the cement as perfect, only 

 &£emin;; harder.
