“ When, therefore, they make a subscription, and issue county bonds in payment, it may fairly be presumed, in favor of an innocent purchaser of the bonds, that the condition which the law attached to the exercise of the power has been fulfilled. To issue the bonds without the fulfilment of the precedent conditions would be a misdemeanor, and it is to be presumed that public officers act rightly. ”

“ If, when the law requires a vote of taxpayers before bonds can be issued, the supervisor of a township, or the judge of probate of a county, or other officer or magistrate, is the officer designated to ascertain whether such vote has been given, and is also the proper officer to execute, and who does execute, the bonds, and if the bonds themselves contain a statement or recital that such vote has been given, then the bona fide purchaser of the bonds need go back no further. He has a right to rely on the statement as a determination of the question. ”

“ Eaves, that a presumption arises from the mere fact of subscription and issue, though not a conclusive one. Independent of authority such a presumption exists and is but an instance of the broader presumption that officers charged with the performance of a public duty perform it correctly. In the case at bar the judge of the county court was charged with the duty of issuing the bonds upon the performance of the condition precedent. ”
