338 HORTICULTURAL TOUR. 



which strangers would certainly encounter at Plymouth or 

 Portsmouth. We walked through the extensive ware- 

 houses, and into the dock-yard, where several sloops of 

 war and one linc-of-battle ship were on the stocks. Even 

 the model-room was thrown open to us. Here the model 

 of the camel, by means of which ships of the line are en- 

 abled to get over the Pampus or bar of the Zuyder-Zee, 

 was explained to us. It consists of two long vessels like 

 barges, but without hatchways, and connected below by 

 strong chains : water being admitted, the camel sinks and 

 is then passed under the bottom of the war-ship ; the water 

 being now pumped out of the camel, its buoyancy is so 

 great that it raises the ship a good many feet, and enables 

 her to pass the bar. The officer in attendance was evi- 

 dently not ill pleased to be able to shew us as a trophy, a 

 letter written by James, Duke of York, as Governor of the 

 East India Company, in 16G4, addressed to an Indian 

 Prince, and which, from the contents, appears to have 

 been accompanied with the present of a crown ; the Eng- 

 lish vessel conveying the present having been captured by 



Admiral De Ruvter.

Close by is the marine seminary, called the Kzvcck-school, 

 for the instruction of boys in naval matters. There is 

 here a large model of a frigate, equal in size to an ordina- 

 ry sloop, completely rigged and fitted out ; by means of 

 which the young men learn the names and management of 

 the multitudinous tackle and sails of a war-vessel. The 

 scholars wear a uniform, sleep in hammocks, mount guard, 

 and are altogether under the same discipline as if they were 

 al tea. 



We proceeded to view the harbour, and to pay cursory 



visiu t'> ome of i he many public establishments. In the 



treel oexl to the harbour, are some elegant houses; but
