238 as pails, tubs, and then furniture. Barks, as for tanning or dyeing, seeds and gums, and the wood pulp for paper are on exhibition. Among the miscellaneous products deserving mention are fibers, as used in basket-making or cane work.

Forestry as a science is made the basis of a series of exhibits. These include timber culture, tools used, and methods employed in planting and caring for trees. And finally lumbering as a science finds a place in the scheme followed in this department. This includes the tools used in lumbering and the methods employed, as well as exhibits illustrating the tan-bark industry, the turpentine industry, and the charcoal industry. So it happens that there is much that can be learned by the student who will devote a little time to the analysis of the exhibits in the building devoted to the products of the mines and the forest.

A visit to the Agricultural Building reveals to the interested observer those products of the soil that are for the most part the result of cultivation, and so we find exhibits of cereals—wheat, oats, barley, and the like—and then their immediate products: bread, pastes such as macaroni, and starches. The sugar-yielding plants, together with honey and the manufactured product, as candy and other confections, come next in order. The root crops, such as potatoes or beets, and the vegetables, are of much importance. Preserved meats and food preparations, dairy products, spices, tea, and tobacco are among the articles on exhibition.

Who will gainsay the fact that the farmer can not do otherwise than learn much from a visit to the home of the products of the soil? It it also customary to include a live-stock exhibition during some period of the exposition.

Mention has been made of the building devoted to the finished products of manufactures and of the buildings in which the crude materials are displayed. Besides these there are usually several buildings devoted to the exhibition of the means by which the original substances, whether from the mine, forest, or farm, are made up into the commercial product for the merchant. One of these is called the "Transportation Building," and in it we find the various means by which the raw materials are conveyed to the factory. From the lower forms of transportation of which man is the motive power, such as the wheelbarrow, upward through the various forms of vehicles of which the power comes from horses and other animals, until as the topmost member of the series is shown the magnificently equipped train of railway cars, provided with all the conveniences that modern
