Show Church Ventilation. ' The proper Tenlilation of all build ings is a subject deserving the attention atten-tion of those who are to occupy them. Private residences are not so often crowded, and do measurably well with do special provision. But public pub-lic buildings theatres, lecture rooma and churches, are as a general rule poorly adapted for ventilation. This is a fact particularly noticeable throughout Utah, acd especially in Mormon churches, or, as they are called, meet ill g bouses. These houses too often have low ceilings, small windows, and no openings above to allow the foul air to escape. It is generally accepted that each person requires 2,000 cubic feet of pure air each hour to properly sustain sus-tain life. This estimate may be large, but it will do for consideration, A room 120iSO feet, with ceiling fifteen fif-teen feet high, contains 1-44,000 cubic feet, or enough air to supply one person for seventy - two hours. Allowing that one-half the above stated quantity is sufficient, it would last 144 hours. If during dur-ing thia lime, the room be half refilled by fresh air coming through openings around doors and window, the amount would be sufficient to last 2S8 hours. Such a room will Beat at least 2,000 persons, who would exhaust ex-haust the pure air in leea than ten minuteB. After that time they breathe and rebreate air charged with carbonic acid. It is to the effect of this that so much drowsiness and sleeping in chuch ara due, to a great extent. While good ventilation can be secured by lowered windows and open doors, even those precautions are neglected. People attend meeting, meet-ing, come away feeling dull and think that if no better effect can be produced pro-duced they would belter stay at home. And many of them do. Pure afr is bountifully supplied, is free only for the taking, and it is strange that such luxuries should bo denied ua. To those interested there is nothing more interesting than a good sermon from an earnest speaker in a room where the air is sweet and invigorating. But there is no sacrilege greater than that of trying to instil God's words to improve man's spiritual nature, while at the same time you compel him to inhale those vapors which corrupt I him physically. |
