These proportions are fully represented, iu the Gokstjul .ship, which so 

 beautifully illustrates the art of shipbuildiug in the north, and of which 

 Mr. Nicolaysen ou page 17 of his description of the northern Longship 

 from Gokstad. justly and proudly says: 



''That there may yet be found in many parts of our country, near the 

 coast, tumuli containing ships in tolerable preservation is by no means 

 uncertain. . . . Certain, nevertlieless, it is that we shall not disin- 

 ter any craft which, in respect of model and workmanshi|>, will out- 

 rival thiit of (iokstad. For, in the oi)inion of expeits. this must be 

 termed the masterpiece of its kind, not to l)e surpassed by.aught which 

 the shijjbniltling craft of the present age could produce. Doubtless, in 

 the ratio of our present idea, this is rather a boat than a ship; never- 

 theless, in its symmetrical i)roportions and the eminent beauty of its 

 lines is exhibited a perfection never since attained until, after a much 

 later but long and dreary period of clumsy unsha]>eliness, it was once 

 more revivf^d in the clipper-built craft of our own country."
