If before the expiration of such thirty days the company do not give notice of their desire to have such mines left unworked, and of their willingness to make such compensation as aforesaid, it shall be lawful for such owner, lessee, or occupier to work the said mines, or such parts thereof for which the company shall not have agreed to pay compensation, up to the limits of the mines or minerals for which they shall have agreed to make compensation, in such manner as such owner, lessee, or occupier shall think fit, for the purpose of getting the minerals contained therein; and if any damage or obstruction be occasioned to the railway or works by the working or getting of any such minerals which the company shall so have required to be left unworked, and for which they shall so have agreed to make compensation, the same shall be forthwith repaired or removed, as the case may require, and such damage made good, by the owner, lessee, or occupier of such mines or minerals, and at his own expense; and if such repair or removal be not forthwith done, or, if the company shall so think fit, without waiting for the same to be done by such owner, lessee, or occupier, it shall be lawful for the company to execute the same, and recover from such owner, lessee, or occupier the expense occasioned thereby by action in any competent court.
