82 IMPROVED FISHERY HARBOUR ACCOMMODATION 



The reader will not fail to observe that the entrances of the 

 outer and inner harbours are placed not in a right line, but in 

 a diagonal line in respect of each other, the object of which 

 arrangement is to prevent the maximum of effective undula- 

 tion from the point B entering the inner basin on a right line. 



The distance from the point to the inner entrance at C 

 is greater than if the undulation met the wall at a right line, 

 which is of itself a certain gain ; but the most important 

 feature is, that in addition to the fact of these second piers 

 giving successive shelter, the diagonal position of the 

 eastern head will divide the undulation and cause it to 

 diverge laterally at its back. 



The diagonal position of inner and outer entrances with 

 regard to each other, if recognised and applied wherever 

 practicable, would be found a most powerful factor, the 

 writer would submit, in the reduction of the height of the 

 waves in a close harbour. 



TALUS OR SPENDING BEACH. 



If this does not exist naturally on the shore on which the 

 harbour is being constructed, and the inner base line be 

 required for quays, which is very generally the case, such a 

 beach might be provided on the right hand margin of the 

 inner harbour (Fig. 2, facing p. 80), or left (Fig. 3, facing 

 this page), on which the remainder of the undulation, after 

 passing the inner pair of piers, might expend itself. 



Such a talus or incline is very useful, as a vessel could 

 be run on it and stopped without damage, to say nothing 

 of its availability for craft of all kinds to clean and coat 

 the bottoms, repair, or caulk, when required. 



We are accustomed to speak of our fishing craft as 

 boats, but as so large a number of them have now become
