 other system. From a si/lcienlturcil point oj view, the first 

 point for consideratitm is the general suitability of the system,

 ment of the factors of the locality ; temporary, or immediate, 

 financial considerations should only prevail in so far as they 

 do not interfere with the two former considerations.
