Any land sold under R.S. 41:631 shall commence in the corner of a legal division or subdivision of sections and shall be parceled out as follows:
(1) If in a right angle it shall be run at an equal distance on two sides, bounded by the lines of the division to form a square including the number of acres sold.
(2) If in an acute angle, it shall be bounded by the division lines to such distance, and by lines in such other directions as the register may deem most equitable between the land sold and that retained.
The patents for land so sold shall set forth the number and of what parish and shall issue to the school board and its successors, for the use of their district schools.
