bered from 600 to 699. Of these, the first ten include arboriculture and 
forest products; the second ten, pomology; the third ten, agricultural 
products; the fourth ten, land animals; the fifth ten, marine animals, 
fish-culture, &c.; the sixth ten, animal and vegetable products; the 
seventh ten, animal and vegetable fibers; the eighth ten, machines, 
implements, and processes of manufacture; the ninth ten, agricultural 
engineering and administration; the remaining ten are devoted to till- 
age and general management. The total exhibits under these classes 
are from the following countries: United States, 696; Great Britain 73; 
Canada, 297; France, 224; Germany, 161; Austro-Hungary, 53; Switz- 
erland, 24; Belgium, 38; Netherlands, 72; Sweden, 85; Norway, 77; 
Italy, 259; Brazil, 260; Argentine Republic, 632; total, 2,951. The 
aggregate of the Argentine Republic is especially remarkable, nearly 
equaling that of the United States. The great majority of these last- 
named exhibits consist in forest and agricultural products and their 
preparations, especially textile fibers. There are memorials of a wonder- 
ful luxuriance of production, mostly spontaneous. Very few processes 
are illustrated by specimens, and no implements or machinery are pre- 
sented except a single model of a pump. Grand capabilities of produc- 
tion are here indicated, with but little of systematic effort to realize 
their results. 
Arboriculture and forest products.—Under this head the United States 
presents several collective exhibits remarkable for their value and full- 
ness. Kansas has a very fine display of timber from her scanty wood- 
lands. Indiana presents a collection embracing all kinds of timber 
found in the State. Oregon, Iowa, Delaware, West Virginia, and 
Michigan show similar exhibits, but not so systematic or complete. 
The National Timber Preserving Company, of Philadelphia, exhibit 
their chemical method of timber-preservation. The Eastern Burnet- 
izing Company illustrate their method of wood-preservation by fore- 
ing a solution of chloride of zine into the pores, after having previ- 
ously expelled the air and sap. Itis claimed that the chemical enters 
into permanent combination with the ligneous fibers, hardening and 
improving their texture. Canada has a fine collection of rough and sawn 
timber arrangedinabuilding. Several of these are manufactures of wood, 
illustrating rather mechanical processes than original growth. Germany 
sends a specimen of manufactured resins; Austria, two specimens of 
manufactured wood, and some saffron ; Netherlands, some sieve-frames, 
cork, and a plant one hundred years old; Sweden, some fir timber, grown 
at latitude 67°, and a regular sylvicultural collection; Norway, some 
specimens of wood and its manufactures ; Italy, seeds, nuts, leaves, &c; 
Brazil, a variety of samples of native woods and of lumber prepared 
for market. The Argentine collection is especially full, embracing 
numerous systematic collections illustrating the arboretum of large 
provinces. 
Pomology.—The exhibit of Pomology includes fruits of the tropical, 
semi-tropical, and temperate regions. A separate building, called 
Pomological Hall, has been erected, and connected with Agricultural 
Hall by a covered way. It is 200 feet long and 180 wide, giving facili- 
ties for the display of 8,000 dishes of fruit at one time. For the exhibi- 
tion of fresh fruits in their season, special occasions were designated by 
the Centennial Commission, as follows: For pomological products and 
vegetables, May 16 to 24; strawberries, June 7 to 15; raspberries and 
blackberries, July 3 to 8; Southern pomological products, July 18 to 22; 
melons, August 22 to 26; peaches, September 4 to 9; Northern pomo- 
logical products, September 11 to 16; autumn vegetables, September 19
