The extensive docks at the mouth of the river Itchen, to the east of the town, have, of course, greatly increased its wealth.  We saw a magnificent foreign-bound steamer coming out of the docks.  The West India ships start from here, as do other lines of steamers running to the Cape, and to various parts of the world; so that Southampton is a bustling seaport.  There is another river to the west of the town, called the Test; and that joining with the Itchen at the point where the town is built, forms the beautiful Southampton Water.
