We had heard that Yarmouth was likened to a gridiron, and we now saw the reason.  Comparatively few broad streets run north and south; they are, however, joined by one hundred and fifty or more narrow passages, called rows, which run east and west, like the bars of a gridiron.  In many of them the houses project beyond their foundations, so that the inhabitants can almost shake hands with their opposite neighbours.  Most of the rows are paved with pebbles brought up from the beach.  Uncle Tom observed that the word "row" is probably derived from the French _rue_, a street.  In many of them we observed curious pieces of old architecture.  They are now numbered, but used to be called after the names of some of the principal inhabitants.  One is called George and Dragon Row; and in it we noticed a somewhat tumbledown cottage, built in what is denominated the "herring-bone pattern;" the bones or frame being of wood placed in a zigzag fashion, filled up with masonry.  Another row is Kitty Witches Row.  One end is scarcely three feet wide.  It is supposed that this row was inhabited by women, who used to go about at certain seasons of the year, dressed in fantastic fashions, to collect contributions.  Yarmouth carts are formed probably after the model of the most ancient vehicles in the kingdom.  They are long, narrow, and low, the wheels being placed under the seat, so as to occupy as little space as possible.  The shafts are fastened to the axles, and two or three perpendicular pieces of wood--the hindermost being the longest-- support the seat, on which a person can recline at his ease.  It will thus be seen that wherever the horses can go, the cart can follow.
