If on the day appointed to show cause, or any other day to which the matter may be continued, it appears to the court from the inquest or from evidence introduced that the residence of any owner, or the outhouses, inclosures, garden or orchard immediately belonging thereto, will probably be overflowed, or that the health of the neighborhood will probably be endangered, or that any other mill, gin, factory or waterworks will probably be overflowed, the court must not grant the application; but, if such results will not probably ensue, the application must be granted.
