When such reports are filed, the clerk of the chancery court shall thereupon give notice for two weeks by two insertions in some newspaper published in the county or counties in which the land proposed to be included in and added to the existing drainage district is located, calling upon all persons owning the land within the said territory to appear before the chancery court, or chancellor in vacation, not less than ten days after the last publication of said notice to show cause in favor of or against the extension of the boundaries of said district so as to include and embrace their lands therein. If it shall appear to the court or chancellor that the extension of the boundaries of said drainage district, so as to include the additional territory and the construction of the proposed improvements, will be conducive to the public health, to the public benefit, and to the interest of the land and the owners thereof, he shall enter an order extending the boundaries of said drainage district so as to embrace and include said territory, and establishing the same as a part of said existing drainage district.
