April 14th, 1914. — Neap tides : fresh westerly breeze. 

 A float released at half -flood opposite the buoy marking the 

 sewer outfall passed between the 7th and 8th piles of the 

 wooden railway bridge, and 100 yards oif Coes Faen. It 

 then stood out towards the south shore. Another float 

 dropped close inshore opposite the drains from the houses 

 at Aberamflra was carried some yards down river by the 

 eddy, against the set of the tide, then turned and skirted 

 the shore a few yards out. It remained close inshore opposite 

 Aberamffra, and passed 50 yards out from Coes Faen, in 

 the direction of the cockle beds. 



Afternoon. — Ebb tide. A float released after 1^ hours 

 ebb close inshore, opposite drains at Aberamnra, went 

 ashore 20 yards lower down. 



Half-an-hour later a float, dropped opposite the sewer 

 buoy, took a direct line for the Point of Ynys-y-Brawd, 

 where it eddied around, and finally went aground. 



April 6th. — Fresh westerly breeze : flood tide. The 

 float dropped opposite the sewer buoy, on half flood, passed 

 just inside outer line of buoys marking the channel above 

 and below the bridge, and 30 yards off Coes Faen. 



April 7th. Fresh W.N.W. breeze : ebb tide. A float, 

 released about 15 yards outside the sewer buoy on last of 

 ebb, came inshore as far as the point of Ynys-y-Brawd, 

 went 30-40 yards up river with the eddy of the island, and 

 opposite the sewer buoy remained practically stationary, 

 the tide being slack. 



Afternoon. — First of flood. From the sewer outfall 

 the float took a somewhat zigzag course. It passed first 

 just inside the inner of the buoys marking the channel 

 below the bridge, under the furthest arch of the iron rail- 

 way bridge, inside the outer of the buoys marking the
