Many special types of bodies are made for peculiar purposes. These often facilitate loading and unloading, for example tank ears for hauling water, milk, gasoline or other fluids; or trucks fitted with shelves on which are placed trays containing fruits and so forth. As the motor truck enters newer fields of usefulness multiple devices will be developed to lessen the time of loading and unloading. The financial importance to both the owner and the public of keeping the truck moving will no doubt lead to the adoption of these devices providing they are practical and will accomplish the desired result. =Traffic between Towns.=--Wherever the roads are dependable and passable at all seasons of the year truck and bus lines have sprung up to ply regularly between the towns. The length of haul most profitable seems to be that over which the motor can make the round trip each day and have sufficient time at terminals for loading and unloading. Forty to 50 miles for trucks and 60 to 65 miles for buses seem to be negotiable and double these distances are proving to be practicable. In many of the states such enterprises have been declared to be common carriers subject to the laws governing such carriers, and must secure licenses to do business from the public service commissions. It is but reasonable that the public should be safeguarded and these concerns be required to take out insurance or give indemnifying bonds to cover loss of goods to shippers by carelessness or theft or injury to passengers by accident. On the other hand the licensed motor transport is entitled to protection against irresponsible truckers. The modern method of state regulation does not contemplate competition as an economic factor in the determination of rates and routes. The old doctrine of “everyone for himself, and the devil take the hindmost,” is certainly most wasteful. This is about the way that method worked. A starts a bus line between two towns. After he has run it a short time and built up a trade B, seeing his success, decides to put a competing bus on this same route. Then there is a period of competition. Rates may be cut and speeds quickened until each bus is running at a loss. This cannot continue indefinitely. The result is that either one man goes out of business or there is a combination of interests by actual coalescing or by a “gentlemen’s agreement,” so that there is practical monopoly anyway. The modern method is to regulate all common carriers as far as rates and routes are concerned so that each may make a justifiable profit. This may be tending toward socialism and away from individualism; it may be a violation of the Darwinian doctrine of a survival of the fittest. But that is departed from every day. Our cornfields and gardens would amount to nothing if the weeds were allowed undisputed sway.
