indebted for much information, informs us that a strong 

 current sets in towards Drigg and that "coasters in the 

 know are always on the look out when anythnig goes down 

 off Holyhead." The general direction and force of the 

 wind remained much the same as before, but the bottles 

 were liberated nearer the fairway of the Channel, and from 

 No. 8 onwards they were subject to the influence of the 

 (nearly) mid-channel streams and this accounts for their 

 more northerly destination. From No. 12 onwards the 

 destination changed to the south; thus the bottles liberated 

 ofjf Carnarvon Bay did not go so far N. as St. Bee's Head; 

 those liberated offBardsey Island (16 to 18) almost all went 

 into Morecambe Bay, and the last two lots, set adrift near 

 the southern limit of Cardigan Bay, got no further north 

 than Blackpool. This is due, no doubt, to some extent, 

 to the greater distance the bottles had to traverse, but also 

 to the wind, which after the 10th January blew for a time 

 from the E.N.E. to N.W. 



The influence of the wind on the general drift which 

 would follow from the direction of the tidal streams alone 

 is also seen in the case of six bottles set free in a former 

 experiment* by Mr. Scott. The data concerning these 

 are given in the sketch chart (fig. 3). The bottles 

 were set free about 10 miles west of Morecambe light ship 

 on the same day ; their destinations, the direction of the 

 tidal streams and the general direction of the wind during 

 the period when the bottles were apparently at sea, are 

 marked on the chart. Under the influence of the tidal 

 streams alone the bottles would probably have gone ashore 

 near Blackpool or into Morecambe Bay, but the wind 

 during the early part of the period when the bottles were 

 adrift blew from the N., N.E., and N.W., and later on it 

 shifted from N.W. tbrough W. to S.W. The average
