Storm windows should be carefully fitted or they will come far from serving their purpose. If they are of the right sort they will soon repay their cost in easing up the furnace. Preferably they should be swung from the top, both for ventilation and washing and to avoid a check upon egress in case of fire. Some persons object to storm windows on account of the supposed stoppage of ventilation, but that rests entirely with the occupants of the house. They can get plenty of fresh air without letting the gales of winter have their own sweet will.
With floors, walls, and windows determined upon, we have a good start on the interior of our house. But we may only pause to take breath, for we now have to give most careful consideration to two decidedly important factors in our comfort - lighting and heating.
