76 PRACTICAL ARBORICULTURE 
TRANSPORTATION INFLUENCED BY FORESTS. 
There was very much to instruct as well as to interest the visitor at the Trans- 
portation Building of the Louisiana Purchase Exposition. 
One here saw the rude carts and pack animals, which are still used in some 
distant and mountainous countries, as well as the primitive methods of transpor- 
tation of the earlier settlers of our own land, and by their side view the magnifi- — 
cent trains of palace cars and the elegantly equipped ocean steamers of most.mod- 
ern construction. 
The engines and train service of Germany, Great Britain, Japan and United 
States were compared, and every equipment for the safety, comfort and speedy 
conveyance of travelers and economical transportation of freights, shown by all’ 
countries which are engaged in manufactures and commerce. 
Within glass cases were exhibited upwards of an hundred models of ocean 
liners, the models being usually from ten to twelve feet in length. The beauty 
of these miniature steamships, the elegance and finish of the models and their de- 
sign and workmanship could only be equalled by the vessels themselves which 
were represented by these models. 
Lefore the products of the world can be conveyed to distant markets by sail- . 
ing vessels, ocean steamers, or other forms of commerce, there is in every case a 
greater or less distance over which the crude products must be transported by 
some land or water conveyance, the methods adopted by various countries in car- 
rying these raw materials to the sea or to the factory was shown in the Trans- 
portation Building, and made an interesting study. 
The great balloon, which is partly inflated. in the center of the building, rep- 
resents aerial transportation or navigation as is the usual expression. 
Of course there is a limit to the buoyancy of a vessel which must be sup- 
ported by a gas which is slightly lighter than the air, or, as in some proposed air 
ships, lifted by fans which are operated by machinery and this additional weight 
must also be supported as well as the vessel by the same means, and therefore no 
matter how great the interest of the public or how strong the curiosity to see some- 
thing new, vet the practical benefits which can be derived from atmospheric navi- 
gation will always be restricted. Pig iron, wheat. grains. food stuffs, coal, lum- 
ber, textiles, etc., go to make up the world’s great industries which require trans- 
portation, and they will scarcely be carried by balloons to any great extent or 
distance, notwithstanding the craze which impels inventors to enter these mis- 
directed and chimerical channels. 
From Acoma, New Mexico, came an ox cart of the rudest construction, no
