A few thinking men here, in viewing the various systems of co-operation, are surprised that the principle has not yet extended in the Colonies to banking, and are gaining informa tion upon the subject, prior to taking action in the matter, should they see grounds substantial enough for such a proceeding. They are aware that the Co-operative Credit Bank in London is a success as far as it has gone. The repre sentatives of this institution have stated the advantages of their system over joint stock banking. They counted that allj the share holders are equally good and substantial for their liabilities to the Bank, which is not the case with Joint Stock Companies. They take credit to themselves for having predicted, in a journal issued under their auspices, the recent Eanic in the money market at home, which as arisen in consequence of a reckless sys tem of advancing millions of money at dis count on some well-known name without security. Such failures, they say, arose be cause the Banks did not permit the de positors to t participate in the profits, and they were driven into the dangerous practice of continually discounting vast masses of paper, and thus upsetting every honest branch of trade throughout the country. But, under the co operative system, it ia affirmed that no such risks can possibly occur ; they have money always on hand, and the account is never closed. This idea is merely in an embryotic state, but do not be surprised to hear that it is, sooner or later, capable of reaching a condition of more advanced vitality. One of the most outrageous cases was tried here the other day that has perhaps ever fallen under the observation of the majority of your readers.
