Among the best American exhibits are, beginning with the 

 Eastern states, those of Massachusetts, New York, Pennsylvania, 

 North Carolina, Michigan, Minnesota, Missouri, Colorado, Mon- 

 tana, Arizona, Idaho and California ; and in Canada those of the 

 Provinces of Quebec and Ontario. Among the other foreign 

 exhibits that of New South Wales is preeminent in the quality, 

 nature and mode of arrangement of the exhibit. The exhibits 

 of Great Britain, Germany, Norway, Sweden, Denmark, Spain, 

 Greece, Austria, Switzerland, Belgium, Italy, South Africa, Cey- 

 lon, Japan, and other foreign countries, are good as far as they 



go- 

 Many of the mining exhibits of both states and foreign coun- 

 tries are divided, and put partly in the Mines and Mining Build- 

 ing and partly in the individual buildings of the states or coun- 

 tries in question. - Such a course is a great mistake, as it renders 

 the exhibit in both buildings imperfect, and those who see the 

 exhibit in one building without knowing that it is supplemented 

 in another, receive an incomplete, and therefore an erroneous, 

 idea of the products of the country represented. Each mining 

 exhibit should be kept together, whether it be in the Mines and 

 Mining Building or in another building. 



The exhibits of the New England states are naturally repre- 

 sentative of less economic value than those of some of the other 

 states, because, with the exception of building and ornamental 

 stones, most of their mining products are of subordinate import- 

 ance ; but at the same time they display what they have in a sys- 

 tematic and consistent manner. The Massachusetts exhibit is 

 thoroughly characteristic and well arranged, showing not only 

 the economic products, but also many rocks and minerals of 

 purely scientific interest. The Maine exhibit is also character- 

 istic of the state, while the New Hampshire and Vermont exhib- 

 its are small but appropriate, consisting largely of building 

 stones, with mica and other minerals from New Hampshire. The 

 granite of New Hampshire and the granite and white marble of 

 Vermont are displayed on a small but sufficient scale. 



Coming westward, the New York exhibit is the first one we
