(fig. 109.) is built in a similar 

 situation to the other. It is oval 

 in ground plan, both no 

 at top (fig. 110.) and 

 bottom (fig. 111.); with 

 doors to the fuel-cham- 

 ber and ash-pit (fig. 109. 

 efi\ and an arched cover 

 to the top ( fig. 1 1 2. g), 

 which moves on small wheels 

 drawn off and on by wind- ill 

 lasses (hh), and has two small fT^ 

 openings, serving as chimneys, 

 for the exit of the smoke (ii). 

 The height of the kiln is thirty- 

 five feet : the short diameter at 

 the fuel-chamber is twenty-two

inches (fig. 111.); at ^ ie height of 



113 



twenty feet the short diameter has 

 gradually extended to five feet 

 (fig. 109.), and this dimension is 

 continued to the top, where the 

 oval is nine feet by five feet 

 us (fig. 110). As the 



;,, . fuel-chamber to 



^TT this kiln is very 

 broad in propor- 

 tion to its depth, 

 three separate 



doors or openings 

 become necessary 

 (fig. 113.), as well 

 as advantageous, 

 for more speedily 

 and easily drawing 

 out the lime. 



In some cases, 

 instead of a mov- 

 able cover, a per- 

 manent roof of ma- 

 sonry (fig. 114.) 

 may be adopted. 

 This roof should 

 have proper openings to admit 



the supply of lime and fuel, and these mav be closed bv
