24 LANDSCAPE GARDENING.

 or hand-lamp in the grate or open fireplace, or a coil or 

 other heating appliance in a separate flue, pure air will be 

 constantly supplied; but if the cold-air box is kept closed 

 and no adequate escape is provided, the closely built house

 The most approved method of arranging the heat-supply

 and passes out on the opposite side, the current of heated 

 air may go directly across the room in a narrow current and 

 the air at the sides of the room be imperfectly renewed.

Steam, hot water, and hot-air furnaces are all largely 

 used for heating dwellings, and each has strong advocates 

 among practical and scientific men, but which of them will 

 give the best results depends upon so many conditions that

In many homes the loved inmates are often in a few
