NO. I AIR AND TUBERCULOSIS — HINSDALE I23 



The evolution of the tent and open air shelter into the tent house, 

 shack, and cottage, is an interesting feature of the open air treatment 

 of tuberculosis. 



"Lean-to." — The open air shelter and "lean-to" are somewhat 

 alike. The latter has been long used by sportsmen and others in 

 our northern forests, and has been greatly amplified for sanatorium 

 purposes. The roof of the " lean-to " slopes directly back from its 

 front or there may be a ridge placed close to the front or southerly 

 side of the structure. The roof slopes well toward the back, but is 

 short in front and allows free access of air and light. Canvass or 

 screens are arranged to hang in front as a protection from wind or 

 rain, and to insure privacy. For a full description of a " lean-to " 

 the reader is referred to Dr. H. M. King's description with plans in 

 " Some Methods of Housing," Charity Organization Society, New 

 York. 



Excellent " lean-tos " or open air shelters are in use all the year 

 at the Royal Victoria Hospital, Edinburgh, Scotland, as seen in the 

 illustration kindly supplied by Sir Robert Philip. (See plate 56.) 



Pavilion tents are amplifications of the tent cottage, and are 

 adapted for ten or twelve beds. As described by Mr. Homer Folks, 

 they are sixteen by thirty-two feet long; the walls are eight feet 

 high ; the roof is fifteen feet high at the ridge and the floor of the 

 tent is sixteen inches above the ground with free citculation of air 

 underneath. 



Tent Houses adapted for use in the New England and Middle 

 States are naturally different from those in use in New Mexico and 

 Arizona, where rain and snow are uncommon. The accompanying 

 illustrations show a row of six tent houses and a single tent house 

 at the U. S. Public Health Sanatorium at Fort Stanton, New Mexico, 

 for consumptive sailors, under the care of the United States Public 

 Health Service. The roof has a slight incline and the sides are ar- 

 ranged to give free ventilation as well as shelter when required. 



Trolley Cars. — Superannuated and disused trolley cars were first 

 used for tuberculosis patients by Dr. W. H. Peters, of Providence, 

 Rhode Island, at the Pine Ridge Camp near that city. With slight 

 alterations and at very little expense these cars may serve a useful 

 purpose in connection with the outdoor treatment of tuberculosis at 

 all seasons. Once located on a convenient site they have many ad- 

 vantages over the ordinary shack, affording a maximum of light and 

 air and good protection against storms with their adjustable windows 

 and doors. The author visited Pine Ridge Camp and can testify to
