nishing, and at what rate ? 

 XI. If diminishing, is this due partly or 



entirely to artificial abstraction ? 



(&e No. 13).

b. Their length. 



c. Their distance apart. 



d. Their height — 



(1) When built. 



(2) To leeward above the 

 shingle. 



(3) To windward above the 

 shingle.

built. 



f. The influence which they exert. 



13. If shingle, sand, or rock is being

b. The nature and height of the

c. At what rate the erosion now 



takes place. 



d. What data there may be for 



determining the rate from early 

 maps or other documents. 



e. Is such loss confined to areas 



bare of shingle ? 



15. Is the bareness of shingle at any of 



these places due to artificial causes ? 



a. By abstraction of shingle. 



b. By the erection of groynes, and 



the arresting of shingle else- 

 where. 



16. Apart from the increase of land by 



increase of shingle, is any land being- 

 gained from the sea ? If so, state — 



a. From what cause, as embanking

what date. 



17. Are there ' dunes ' of blown sand in 



your district ? If so, state — 



a. The name by which they are 



locally known. 



b. Their mean and greatest height, 



c. Their relation to river mouths ■ 



and to areas of shingle. 



d. If they are now increasing. 



e. If they blow over the land; or 



are prevented from so doing by 

 ' bent grass ' or other vegeta- 

 tion, or by water channels.
