wanting to any one of its widely scattered nations. One may say 
that such was the physical establishment of the human race upon 
this world. The great triumph over nature was accomplished by 
this process. 
In accordance with this history of development, the present 
exhibition is to present the results of human-industry from its 
earliest appearance, representing them in five departments, viz. : 
The department of archzclogy and ethnology. 
The department of agriculture. 
The department of architecture. 
The department of model homes. 
And finally, the department of machinery and manufactures. 
We can readily see what interest attaches to the department of 
manufactures and machinery, if we are at all familiar with the pro- 
gress of our species, with the history of his supplies of clothing 
and daily food, of how our ancestors lived, and how the first men 
were, as it were, turned loose upon the world to shift for them- 
selves. We know that they lived and survived, and that we are 
standing, to-day, surrounded by all the conveniences of civilization. 
We anticipate that the department of machinery and manufac- 
tures will elucidate the subject in the extensive space which has 
been devoted to it within the building. 
We now pass to the departments devoted to the supply of the 
necessities of his mind. It is evident that man in his first existence 
upon earth, began with sufficient rationality to enable him to sup- 
port and protect himself against fearful odds; for as of all animals 
the least perfectly furnished with natural defences, he was com- 
pelled to rely upon his own skill and activities. He inherited what 
he had to start with; and doubtless found abundant necessity for 
using it in his combats with the lions, tigers, hyenas, wild oxen 
and bears which sharéd with him the field and forest. The brain, 
at some periods of its life, is, probably of all organs of the body, 
the most capable of growth changes, as it is most susceptible to 
sense impressions. Hence it is developed by exercise to a re- 
markable degree. The development of mind under use is familiar, 
though not sufficiently so, to us all. Its degeneracy in conse- 
quence of disuse is equally well known. As man’s life has been 
from the start a struggle against the forces of nature, without 
weapons or protection, save those of his own making, so man’s
