238 POPULAR SCIENCE MONTHLY. 



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 illus- 

 trating the tan-bark industry, the turpentine industry, and the char- 

 coal 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 ob- 

 server 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. Then come the plants yielding fibers, as cot- 

 ton and the like; but we hasten on to make mention of the exhibits 

 of implements used in agriculture and its special subdivisions, such as 

 horticulture, viticulture, floriculture, and arboriculture. 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 custom- 

 ary to include a live-stock exhibition during some period of the ex- 

 position. 



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
