24 THE BUTTERFLY HUNTERS. 



of a saw-mill, complete in all its parts, with the exception 

 of the great wheel, the materials for which were lying on 

 the workbench under the window. Tom was immediately 

 interested in the neat workmanship and ingenuity of the 

 model, which he examined with the greatest attention. In- 

 side, everything was in perfect order, and ready to be put 

 in motion, and Tom proposed that they should spend the 

 rest of the morning in finishing the wheel. Hal at once 

 agreed, and immediately set to work. The model was 

 about three feet in length, and about eighteen inches in 

 height. One side and one end were open. The other 

 side and end were boarded up, and the roof was neatly 

 covered with miniature shingles. The great wheel, which 

 was to be on the side which was boarded up, was twelve 

 inches in diameter. It was constructed on the "overshot" 

 principle, and the buckets were about two inches in width 

 and nearly an inch in depth. The separate parts were 

 already finished, and Hal had only to put them together 

 with neat wooden pegs. While at work he explained that 

 he had built a splendid mill-dam on the Mountain Stream, 

 where he intended to set his mill. The foundation was 

 all ready, and as soon as the wheel was finished and se- 

 cured to the shaft they could set the mill in its place and 

 commence sawing miniature pine logs.
