• Wé think the instruction to the jury by the sheriff authorized the jury to regard the cost of filling the petitioner’s land, under the St. of 1873, a. 304, as a part of the value of the land, to be added to what its value would have been without the filling. This instruction was erroneous. The St. of 1873 was passed, requiring the land to be filled for the purpose of abating a nuisance. It was required, not for its special local benefit to that estate, but for the public good. The land filled may or may *580not have been improved by the filling to the extent of the cost of the filling. That was done wholly alio intuitu. The fact that the owner was required by law to do it does not add the cost of doing it to the value of the land. If an act had been passed by which his whole establishment was liable to be declared a nuisance, requiring abatement by removal to some more remote position in reference to population, and if, after the removal of his buildings, a way had been laid out over their former site, the value of the land would not involve the cost of putting it into the situation in which the public authorities found it, when it was taken for a public use. It is not the case of expenditures made in adapting land and buildings to the uses to which they are applied. The instruction to the jury should have been to appraise the value of the land as the land was at the time of the taking. Whether the expenditures which had been made upon it were wise or unwise, whether voluntarily or compulsorily made, or whether made for one or another purpose, the cost of snch expenditure is not necessarily to be taken as additional value to the land, as it would have been without such expenditure. Verdict set aside.
