in its
technical and non-aesthetic aspect, maps; physical, moral and social
condition of man. Fifty classes, 300 to 349 inclusive, fence in this
field of pure reason. Department IV., Classes 400-459, covers sculpture,
painting, photography, engraving and lithography, industrial and
architectural designs, ceramic decorations, mosaics, etc. V., Classes
509-599, takes charge of machines and tools for mining, chemistry,
weaving, sewing, printing, working metal, wood and stone; motors;
hydraulic and pneumatic apparatus; railway stock or "plant;" machinery
for preparing agricultural products; "aerial, pneumatic and water
transportation," and "machinery and apparatus especially adapted to the
requirements of the exhibition." VI., Classes 600-699, assembles
arboriculture and forest products, pomology, agricultural products, land
and marine animals, pisciculture and its apparatus, "animal and
vegetable products," textile substances, machines, implements and
products of manufacture, agricultural engineering and administration,
tillage and general management. Under Department VII., Classes 700-739,
come ornamental trees, shrubs and flowers, hothouses and conservatories,
garden tools and contrivances, garden designing, construction and
management.

The accumulated experience of past expositions, seconded by the judgment
and systematic thoroughness apparent in the preparations for the present
one, makes this a good "working" classification. It has done away with
confusion to an extent hardly to have been hoped for, and all the
thousands of objects and subjects have dropped into their places in the
exhibition with the precision of machinery, little adapted as some of
them are to such treatment. Very impalpable and elusive things had to
submit themselves to inspection and analysis, and have their elements
tabulated like a tax bill or a grocery account. All human concerns were
called on to be listed on the muster-roll and stand shoulder to shoulder
on the drill-ground. Some curious comrades appear side by side in the
long line. For example, we read: Class 286, brushes; 295, sleighs; 300,
elementary instruction; 301, academies and high schools, colleges and
universities; 305, libraries, history, etc.; 306, school-books, general
and miscellaneous literature, encyclopaedias, newspapers; 311, learned
and scientific associations, artistic, biological, zoological and
medical schools, astronomical observatories; 313, music and the drama.
