Premiums for JL HE miseries, to which children employed within the flues- 

 ehinjaeys. 'f^ cleansing chimnies are liable, induced the Society for the 

 Encouragement of Arts, he, to offer premiums in the year 

 1808, to obviate the necessity of so cruel a practice. In the 

 year I8O6, the gold medal was adjudged to Mr. George Smart, 

 of the Ordiuance Wharf, Westminster-bridge, for the greatest 

 Jiumber of chimneys cleansed under his direction by mechani- 

 cal means, and a particular account of the method used by 

 him for this purpose will be found in the 23d Volume pi the 

 Society's Transactionsf. During the present session, a gold 

 medal has also been voted to hijn for the be&t machine pro- 

 duced to the Society for the intended purpose; an explana- 

 tory engraving of which having been given in the volume 

 above-mentioned, renders one unnecessary here:^' T|)e follow-
