England. A routine has been instituted which provides for the timely trans- 

 mission to the Bureau of all data called for, and arrangements have been made 

 with the Ministry's statistical officers to ensure that it shall be presented in the form 

 desired. 



V. It is recommended that the Bulletin Hydrographique should contain monthly 

 mean values of the sea level from existing observations. 



England. The Bureau has been put in communication with the Ordnance 

 Survey with a view to obtaining monthly mean values of the sea level at three 

 English stations. 



Other hydrographical work: 

 England. The arrangements for collecting surface samples on steamship 

 routes have been revised and certain modifications introduced in order to keep the 

 number of samples within workable limits. The following routes are now in operation : 



North Sea — Tyne to Christiania (as far as the great Fisher Bank). 

 English Channel — Newhaven to Dieppe. 



Southampton to Havre. 



Southampton to St. Malo. 



Liverpool to Charente (across the mouth of the Channel). 



With the co-operation of the Air Ministry surface samples and temperatures 

 are taken along two Atlantic routes, and under the supervision of Professor John- 

 stone along three routes across the Irish Sea. Copies of data are sent to the Bureau, 

 to the Atlantic Slope Committee and to others concerned. 



The routine observations on the Research Ship have, however, been dropped, 

 as they were found to be too scattered to serve any useful purpose. 



In order to throw light upon the unusual scarcity of herrings, a cruise was 

 carried out between October 4th and 10th along lines from the Norfolk coast to 

 west of the Dogger, then north of the Dogger to the Great Fisher Bank. Intensive 

 hydrographical observations were made at 22 stations and oxygen samples were 

 collected from the deeper water layers. Collections of plankton were also made. 

 The results have been worked up in connection with other hydrographical data 

 obtained from the Light Vessels, with a view to comparison with the conditions 

 in former years. 



A special cruise from Tyne to Naze of Norway was carried out in May. This 

 cruise will, it is hoped, be the first of a series of annual cruises devoted to general 

 hydrography in the northern part of the region. The stations are so placed as to 

 form a basis for hydrodynamical determination of currents, as well as to sample 

 the salinity of the area on an adequate scale. 



Ireland. In accordance with the proposals agreed to by the Hydrographie
