Sou HEATING ROOMS BY STEAM. 



History «nd ac- After having ascertained these results, the memorialist, 

 m^od of hit- ^'^ 1800 drew a plan similar to that jiow presented to the 

 iag Tftoms by Society, and sent it to Glasgow to his employers, who 

 iteam. - ^gj.g ygj.^ doubtful of the success of the scheme. They 



imraediately published the discovery in the Glasgow news- 

 papers, inviting cotton spinners, and others interested, to 

 inspect the plan. In consequence of this public intimation 

 of the method having been successfully practised, a num. 

 ber of cotton spinners turned their attention to it, and 

 adopted it with various modifications, according to the con- 

 venience of their mills, or other notions of improvement. 



The memorialist aiforded to every person who desired it, 

 all the information on the subject which he possessed. His 

 general recommendations were to detach the condensed 

 water, in returning it to the boiler, as much as possible 

 from the steam ; and where tin pipes, or others of similar 

 ■strength, were used, to secure them carefully with safety 

 valveiS. 



There are obvious defects in the application of the prin- 

 ciple, as practised in the instance described above. Of 

 some of these the memorialist was perfectly aware at the 

 time of the first construction of the apparatus, though it 

 was out of his power to remedy them; and he has thought 

 it proper to give a detail of the first successful experiment 

 exactly as it took place. 



From the pipes being all in one end of the house, the 

 heat was unequally diffused, and a considerable time 

 elapsed, after their being first heated, before it reached the 

 other end of the rooms. But, as the mill had barely room 

 enough for the spinning machinery, it was impossible to 

 erect the pipes in any other situation, or to convey them 

 aJong the rooms, so as to produce a more equal distribu- 

 tion of heat. This, however, can be so easily effected, 

 ■when there are no obstacles, such as have been mentioned, 

 that it is scarcely necessary to enter into any detail of the 

 means. It may be barely mentioned that the memorialist has 

 fitted up the apparatus in two cotton mills, which are now 

 Tinder his management, belonging to George Houston, Esq. 

 and Co. of Johnston*, in a manner which completely dis-i 

 tributes the heato la one of these mills, consisting of six
