VENTILATION. 189 



provision for the constant introduction of fresh air. Houses 

 will be constructed, which, although more expensive in the 

 first cost, will be far cheaper in the end, and by requiring 

 a much smaller quantity of fuel to warm the air, will enable 

 us to enjoy the luxury of breathing air which may be duly 

 tempered, and yet be pure and invigorating. Air-tight and 

 all other lung-tight stoves will be exploded, as economizing 

 in fuel only when they allow the smallest possible change of 

 air, and thus squandering health and endangering life. 



The laws very wisely forbid the erection of wooden 

 buildings in large cities, and in various ways, prescribe such 

 regulations for the construction of edifices as are deemed to 

 be essential to the public welfare ; and the time cannot, I 

 trust, be very far distant, when all public buildings erected 

 for the accommodation of large numbers, wiH be required 

 by law, to furnish a supply of fresh air, in some reasonable 

 degree adequate to the necessities of those who are to oc- 

 cupy them. 



I shall ask no excuse for the honest warmth of language 

 which will appear extravagant only to those who cannot, or

 the highest enjoyment, not only of physical, but of mental 

 and moral health. The man who shall succeed in convinc- 

 ing the mass of the people, of the truth of the views thus 

 imperfectly presented, and whose inventive mind shall de- 

 vise a cheap and efficacious way of furnishing a Copious 

 supply of pure air for our dwellings and public buildings, 

 our steamboats and' railroad cars, will be even more of a 

 benefactor than a Jenner, or a Watt, a Fulton, or a Morse. 



To return from; this lengthy and yet I trust not unprofita- 

 ble digression. 



In the ventilation of my hive, I have endeavored, as far 

 as possible, to meet all the necessities of the bees, under 

 the varying circumstances to which they are exposed, in out
