disregarded in the improvement works proposed. The stream 
flows from the left bank at Connah’s Quay obliquely across 
to Daw Pool, which is, presumably, a permanent feature ; 
it then re-crosses to the left bank near Mostyn Deep. The 
proposal is to have a continuation of the present straight 
channel which now extends as far as Connah's Quay and to 
continue it onwards to Mostyn Deep. The construction and 
the maintenance of this would, of course, be very costly. If 
it were made there would still be need for a channel on the right 
side, were it only for the backwater on the Gayton sands. My 
suggestion is to adopt Nature’s hint and to have the principal 
channel through Daw Pool. A low-water groyne from a point 
on the shore near Bagillt obliquely across t(j wards Daw Pool, 
approximately parallel with the line of stream, as shown, 
would effectually prevent any through-passage of stream or 
tide on the left side of the estuaiy. The backwater which 
would flow on that side would include a little stream now 
flowing into the main one opposite Bagillt, and would corre- 
spond to the backwater of the right side of the estuary on the 
Gayton sands. The vanity of attempting to suddenly narrow the 
tidal area has a melancholy illustration in the Broken Wall, the 
line of which is seen crossing the estuary opposite Connah’s Quay. 
The line of a river, at any point in its course, may have 
been decided by the line which it has taken higher up the 
stream, and, also, by the line which it will take lower down. 
This may be illustrated by a diagram, and the principle may, 
I think, be applied to the Humber. Fig. 9 represents a river 
having a settled course from a to b and from c to d, which has
