mer use by blocking up at each comer, and lowered again for the winter. 

 Whatever the height of the runner, the burner box should be taken 

 out before the house is moved. If left in, it might be bent out of 

 shape by striking stones or uneven places in the land. To remove the 

 burner box, raise the hover, lift out the stem, disconnect the piping at 

 the union coupling, unhook the wire and withdraw the box. Care 

 should be taken that the wheel valve next to the tank is closed before 

 the pipe is disconnected, and that the lead gasket is not lost out of 

 the union coupling. 



In Fig. 87 is shown one of these houses built with vertical roof boards 

 not covered with paper. This construction is not so warm as the house 

 covered with paper, and it requires better and more expensive lumber. 

 When placing the roof boards vertically instead of horizontally, use 

 the type of rafter construction shown in Fig. 106. Only one piece need 

 be used for the ridge, however, unless the open peak is desired.
