INLAND TRANSPORT SERVICE 



" If they flourish not, a kingdom may have good limmes, but will have empty 

 veines and nourish little." BACON. 



WE have seen reason to consider the animal body as a country 

 containing numerous towns or cell-communities, each busily 

 engaged on its specific staple industry and connected with one 

 another and with the seat of government by an extremely efficient 

 means of communication the nervous system. Such a country, 

 on account of its complex nature, must have a system of transport. 

 Raw materials from outside must be brought into the country and 

 some means must exist for sorting out the imports and forwarding 

 the suitable ones to the appropriate cell-communities, etc. It 

 is convenient to carry still further this simile of a country. 



It is obvious that some imports may arrive from overseas 

 ready for use and have only to be handed to the distributors for 

 transmission to the consumer. Others again have to undergo 

 some change before they can be transported inland. That is, 

 there are two classes of raw material arriving at the same port, 

 viz. : gas and liquid-solid food. These are handled by different 

 gangs of labourers. The oxygen is sent directly to the inland 

 transport service, while the food material is sent to a series of 

 factories where it undergoes partial manufacture and is repacked 

 in smaller containers, before being handed to the same inland 

 transport service as the oxygen. Just so, iron ore may be shipped 

 to the Clyde, from which it passes through a series of factories, 

 in which it is partially purified, smelted, etc., and then sent as 

 pig-iron, say to Sheffield, for final treatment, before being distri-
