PAVING SERVICE.

The following is a description of the most important work done during the year:

GRANITE BLOCK PAVEMENT.

Albany street, from Broadway to about 75 feet south of Troy street. (See "Assessment Streets.")

Bremen street, from 230 feet northeast of Maverick street, across Porter street is about 1,239 feet in length, with a roadway 24 feet and sidewalks 7 to 9 feet in width. A contract for paving this street was awarded to Coleman Brothers, Inc., May 13, 1921. The contractor did the excavating, and reset the edgestone. The roadway was paved with second-hand granite block with grout joints on a gravel base. Artificial stone sidewalks were laid on the north side and on the south side the bricks were relaid. Work was commenced May 12, 1921, and completed July 11, 1921. The straight edgestone, circles and corners were furnished by the city and delivered on the line of work. The second-hand granite blocks were hauled by the contractor from Chelsea street. All other materials were furnished by the contractor. The sidewalks and roadway were laid under a five year maintenance guaranty. The former surface of this street was macadam roadway with brick sidewalks.

Clarendon street, from Stuart street to Boston & Albany Railroad Bridge. (See "Assessment Streets.")

Columbus avenue, from Tremont street to Centre street, is about 3,170 feet in length. A contract for reconstructing the surface of this street was awarded to John Kelly Company June 24, 1921. Work was begun June 15, 1921, and completed October 17, 1921. This street, 80 feet in width, has a roadway 54 feet in width, with a double track for surface cars in the centre, and is paved with granite blocks, grout joints, on a 6-inch cement concrete base, using the best of the blocks found in the street and reshaping the existing concrete base with new material to conform with the proper grade and crown. The sidewalks are of artificial stone 13 feet in width. The street car tracks were regulated and repaved by the Boston Elevated Railway Company. The city furnished the new edgestone, circles and corners on the line of the work and the granite blocks for replacements at the Massachusetts avenue lot. The contractor did the excavating, took up, cleaned and relaid the granite blocks, set the edgestone, furnished all the materials for the work, other than those furnished by the city, and hauled the surplus
