were never successful in getting any young monkeys. The 

 cause of death was tuberculosis. 



Then we conceived the idea that they should be put out of 

 doors for the purpose of returning closer to nature. Promptly 

 the question was raised as to whether they would stand the rigor 

 of this climate. It was decided that it would not be any worse 

 for them to die in that way than it would be to die with tubercu- 

 losis. Therefore, a pole about fifteen feet long was suspended 

 and fastened in position out in the open ; a roof was fastened to 

 its top and a wire screen extended from this downward to the 

 ground, making an enclosure about ten feet in diameter. On 

 the sides of this upright pole in the center were placed a few small 

 boxes with holes in them sufficiently large for the monkeys to 

 pass in and out, and which served 10 protect them in stormy 

 weather. In winter weather for protection, a frame work made 

 of pieces of wood was built at the base of the center pole and 

 about three feet high and this was covered with straw. What 

 was the result? We have monkeys that have been there for 

 six years and they have brought forth young. What does this 

 teach us? It teaches that we must return closer to natural con- 

 ditions if we desire to be able to protect ourselves against the 

 ravages of disease. 



Disease of Civilization. 



Tuberculosis is a disease of civilization and comfort. It is 

 a disease which is brought about by artificial conditions, and it 

 cannot thrive in man or the lower animals or spread when man 

 or animals are constantly out in the open and living as near as 

 possible to nature as they were intended to live. Under such 

 circumstances their protective forces would be so great that if 

 they should become infected with the disease, it would remain 

 at the point of entrance, as a local disease and harmless. Tuber- 

 culosis always begins as a local disease, and naturally developes 

 very slowly when compared with other diseases. If man or ani- 

 mal should become infected in this local manner, and if they 

 have lived along the lines that I have indicated it would always
