We have spoken of the foul air of court-rooms. What better illustration could be given of the utter contempt with which the laws of bodily health are treated, than the condition of these places? Our lawyers are our highly educated men. They have been through high-school and college training, they have learned the properties of oxygen, nitrogen, and carbonic-acid gas, and have seen a mouse die under an exhausted receiver, and of course they know that foul, unventilated rooms are bad for the health; and yet generation after generation of men so taught and trained will spend the greater part of their lives in rooms notorious for their close and impure air, without so much as an attempt to remedy the evil. A well-ventilated court-room is a four-leaved clover among court-rooms. Young men are constantly losing their health at the bar; lung diseases, dyspepsia, follow them up, gradually sapping their vitality. Some of the brightest ornaments of the profession have actually fallen dead as they stood pleading,--victims of the fearful pressure of poisonous and heated air upon the excited brain. The deaths of Salmon P. Chase of Portland, uncle of our present Chief Justice, and of Ezekiel Webster, the brother of our great statesman, are memorable examples of the calamitous effects of the errors dwelt upon; and yet, strange to say, nothing efficient is done to mend these errors, and give the body an equal chance with the mind in the pressure of the world's affairs. But churches, lecture-rooms, and vestries, and all buildings devoted especially to the good of the soul, are equally witness of the mind's disdain of the body's needs, and the body's consequent revenge upon the soul. In how many of these places has the question of a thorough provision of fresh air been even considered? People would never think of bringing a thousand persons into a desert place, and keeping them there, without making preparations to feed them. Bread and butter, potatoes and meat, must plainly be found for them; but a thousand human beings are put into a building to remain a given number of hours, and no one asks the question whether means exist for giving each one the quantum of fresh air needed for his circulation, and these thousand victims will consent to be slowly poisoned, gasping, sweating, getting red in the face, with confused and sleepy brains, while a minister with a yet redder face and a more oppressed brain struggles and wrestles, through the hot, seething vapors, to make clear to them the mysteries of faith. How many churches are there that for six or eight months in the year are never ventilated at all, except by the accidental opening of doors? The foul air generated by one congregation is locked up by the sexton for the use of the next assembly; and so gathers and gathers from week to week, and month to month, while devout persons upbraid themselves, and are ready to tear their hair, because they always feel stupid and sleepy in church.
