This stone is produced from quarries somewhat recently opened near Harrogate. Several specimens of it were shown at the International Exhibition of 1872.

The quarries produce landings of any size up to 150 feet superficial, steps up to 20 feet in length, sets, paving and building stones.

Some of the stone is white, some of a light green tint, and a bed called the ragstone is specially recommended by the proprietors for heavy engine bases, foundations, etc.
