Show AortrAL experiments biiow that tho ventilation ol railroad cars is seriously defective, especially in cold wealher, and various remedies have been ug- j geated. The Juiilrmul Gazelle proposes a simple plan, which has been tried and indorsed by the Kuperintendcnt of the Richmond, Fredericksburg and Potomac railroad. It consists in simply raising the front window next to the i-tove and letting down the blind. The O'-izete argues that by doing this a plentiful biipply of air will enter under ordinary circumstances, circum-stances, and that this current of cold air going upward and mingling with the hot air asondng from the stove, becomes modified in temperature so thnt the passengers experience no discomfort from the ingress of tho iife-givitig atmosphere. This plan possesses the merits of simplicity and cheapness, and may bo partially efficacious in purifying the atmosphere atmos-phere of cars. Xow let some ono discover a way to rid passengers of the annoyance ol the shower of cinders which sifts through the open windows iuwarm weather. Several remedies have been suggested, but none of them seem to meet the favor of the railroad companies. |
