CHAPTER IV. 

 SHIPS, SHIP-BUILDING, DOCKS, ETC. 



1. On the sea-coast or on the bank of a river 

 you will sometimes find a ship-yard, where ships 

 are built. In the chart a ship-yard appears at 

 the mouth of the large river, on its left bank. 



2. To build a ship, men lay a great, long tim- 

 ber called the keel, on an inclined track or plat- 

 form. To this keel are fastened the ribs, or 

 curved timbers, which form the sides of the 

 ship. The whole is supported and surrounded 

 by a great frame called the stocks.
