The petitioner, a domestic corporation engaged in the manufacture of cotton cloth in the city of New Bedford, delivered to the respondents, the assessors of taxes, within the time prescribed in their notice to taxpayers for the year 1926, a fist of its taxable property which did not include its real estate, and no question is raised that the list was not verified. G. L. c. 59, §§ 29, 31. The assessors valued the property for the purposes of taxation as follows: “Real Estate, $594,875 Personal Property, *434$1,265,275”; and assessed a tax thereon in the sum of $51,434.18. The petitioner, claiming that it had been overtaxed, filed with the assessors on February 4, 1927, a petition for abatement. G. L. c. 59, § 59.
This petition was the sole remedy for an excessive valuation of the petitioner’s property. Kelley v. Barton, 174 Mass. 396. G. L. c. 59, § 61. There was no evidence tending to show that the tax list was not filed in good faith, and the petitioner’s failure to include real estate did not deprive it of the right to apply for an abatement of the tax on the personal property listed in the return. G. L. c. 59, §§ 59, 61. Wright v. Lowell, 166 Mass. 298. Blackstone Manuf. Co. v. Blackstone, 200 Mass. 82, 93. We find nothing in conflict with our decision in Central Bank v. Lynn, 259 Mass. 1, cited by the respondents, where it was held that a fist not sworn to was not in conformity with G. L. c. 59, § 29, and the refusal of an abatement was sustained.
It was the duty of the board of assessors, who are public officers, to act within a reasonable time upon the petition, and to determine whether an abatement should be granted or refused. Milford Water Co. v. Hopkinton, 192 Mass. 491, 497, 498. Cox v. Segee, 206 Mass. 380, 382. Dexter v. Beverly, 249 Mass. 167. The petition for abatement was filed February 4, 1927, but the assessors took no action, thus depriving the petitioner of exercising its right of appeal from their decision as provided in G. L. c. 59, §§ 64, 65. The respondents having introduced no evidence explaining or justifying the delay, their request for a ruling that the court had no jurisdiction to entertain the petition or to issue a writ of mandamus to compel them to pass upon the question of abatement was denied rightly. Crocker v. Justices of the Superior Court, 208 Mass. 162, 164.
Exceptions overruled.
