. The large tiles burn to 121 



inches long, 5 inches high;, and 3i inches opening ; the small 

 tiles to 12 inches long, 3^ inches high, and 2^ inches opening; 

 the bottom tiles to 10 J by 5 inches, and three-quarters of an inch 

 thick. The large tunnel-tiles when burnt are 12^ inches long, 7 

 inches high, and 9^ inches opening ; the small, 1 1 inches long, 6 

 inches high, and 8 inches opening. 



9. Both wood and coal are burned in the kiln, the latter re- 

 quiring iron bars along the arches and doors, as shown in C, 

 Plan 3. This kiln takes about 2000 fir-top fagots to burn off, 

 or 1500 of better wood, viz., 1000 fagots, and 2 waggon-loads of 

 round wood ; when burnt w ith coals it takes about 200 fagots, or 

 peat-turf, in proportion at first, and afterwards about 6 tons of 

 coals. The labour of burning is greater with wood than coal, and 

 worth \s. 6d. to 2s. per 1000 more. 



10. The kilnman finds everything but buildings^, earth, and 

 straw, fuel and duty (on bricks), and is paid 26s. per 1000 for the 

 large tiles, 1 5s. per 1000 for the small tiles, and 9s. 6d. per 1000 

 for the bottom tiles. He has also 12s. per 1000 for bricks, and 

 he pays a rent for the house and land. The detail of value of 

 labour in the various processes is thus stated : —
