1905.] THE LOUISIANA I'URCHASE EXPOSITION. 26 1 



detrimental to the human flesh, but they have discovered an 

 invention which quite counteracts that evil, as there is a method 

 which they now use and which they claim will protect the 

 patient from any evil effect from the use of X-rays. 



So we went on through the entire building. Of course I 

 cannot spend time to take up each interesting subject in detail, 

 but there were these three things shown, which have been 

 developed and have greatly progressed since the last world's 

 fair, and are now up-to-date, and in fact the latest things, and 

 as interesting and more real than the tales of the Arabian 

 Nights. 



Some one has said that the particular study of mankind is 

 man. If I were asked what one feature of the St. Louis Ex- 

 position was predominant on its educational side I should say 

 it was the study of man. When the St. Louis Exposition was 

 being constructed its managers found, unfortunately, that they 

 were going to have barely enough room for the large buildings 

 and for what they had projected. You will remember that 

 Washington University was just being completed. The build- 

 ings included a magnificent great stone building in the paral- 

 lelogram, covering some 40 to 46 acres. As the fair pro- 

 gressed, the bounds were increased, and finally this was all 

 taken in and rented for use during the fair. In that building 

 was located the administrative department. They fitted those 

 buildings permanently, so far as the museums were concerned, 

 so that there we found all the relics that could be gotten to- 

 gether, representing prehistoric man and his implements and 

 tools. This scientific department was very carefully made up, 

 thoroughly equipped, and systematically and carefully classi- 

 fied in the regular catalogues, so that one could go through 

 there being sure that such men as Prof. Frederick Starr, Dr. 

 Clinton, and all of those men who are pronounced authorities 

 on the subject, had given it careful attention, and could have 

 the benefit of their researches, their books, their data, and their 

 statistics. In there one could find a very complete collection 

 from the mounds in Ohio, collections which had been gathered 

 as the result of long investigation with reference to the mound 

 builders and early prehistoric man. It is said that they found 

 140 skeletons in two low subterranean terraces. They were 

 first discovered about 1846, and they have been discovered 

 from time to time since. All those were carefully classified.
