roofs but these are apt to drip during boiling which is not only un 

 pleasant for the workers but tends to color the sap in the evaporator. 

 On this account a shingled roof is preferred. It is well to have the 

 walls fairly tight and ventilators of large capacity, the full size of 

 the evaporator, to allow the steam to escape freely. It is well under- 

 stood that the warmer the house the better the ventilation. A cold 

 sugar house is generally filled with steam while in operation. The 

 house should be well lighted. A brick or metal smoke stack should 

 extend well above the roof to assure a good draft as hot fires are necessary

 protection from fire to use cement or brick pavement in front of the 

 fire doors. A drain leading away from the building should be provided 

 to carry off weather water and washings. 



The building of the sugar house should be finished during the 

 Summer or early Autumn so that the furnace or arch may be placed 

 on its foundation before the ground is frozen. The equipping, in- 

 cluding the storing of a supply of fuel, should also be concluded before 

 winter sets in.
