suitable for the facing of quays and piers, and an abundance 

 of greenstone for the exterior work. 



Few persons, if any, worked more continuously or more 

 intelligently in the hope of a harbour of refuge being con- 

 structed at St. Ives, than the late Mr. John Tremearne. 

 He devoted a great deal of the latter part of his life 

 towards the furtherance of the object, and, as a result of the 

 interest he took in the cause, we are enabled to judge of the 

 tidal influences of the locality." 



" The tides run nine hours in a northward, and only three 

 hours in a southward direction, varying their courses from 

 north-west to north-east. The velocity at the Land's End 

 and the Rundle Stone is from two to four and five miles an 

 hour, according to spring or neap tides." 



Mr. Tremearne showed that " the influence of the northern 

 stream extends to some distance south of Scilly Islands, 

 affecting vessels running to make- Scilly. When thick 

 weather prevails this carries them to the northward of the 

 Land's End, into the north channel, before they make the 

 land, particularly when southerly or south-east winds prevail." 



" When the tide is half-ebb in Mount's Bay it turns to the 

 westward, altering its course to the northward as it nears the 

 Land's End, continuing its course for nine hours, therefore 

 giving every facility for vessels coming from the English 

 Channel to the northward of the Land's End. All this tends 

 to show the advantages to be derived from the construction 

 of a harbour of refuge in the Bay of St. Ives." 



" As regards the fishermen, Mr. Ross, M.P., aptly repre- 

 sented their condition when he told the House of Commons 

 it was absolutely deplorable. In the absence of a harbour 

 of refuge, they are often deterred from putting out to sea to 

 pursue their calling. This has been a truism for years, but 

 the drawbacks that have been experienced have been
