at the month of the North Sea Canal and at Flushing ; while on this side 

 of the Channel, extending from Portland to Yarmouth, the port and other 

 authorities at the points selected also undertook the duties of making 

 the necessary observations. 



The results have not yet been all received, and they are not in a suffi- 

 ciently forward state to be presented at this meeting. 



In consequence of the great importance of accurate permanent tidal 

 records at Dover being available, the Chairman of the Committee urged 

 upon the Warden of the Cinque Ports, Lord Granville, that a self- 

 registering tide gauge should be erected at Dover ; a proposal which met 

 with his Lordship's cordial approval and support. 



The Board of Trade have further consented to grant a suitable site for 

 the erection of a self-registering gauge on the Admiralty Pier, and have 

 undertaken to defray the cost thereof. 



The exact form best adapted to the place is at present under considera- 

 tion, but it is confidently hoped that before long a self-registering tide 

 gauge will be permanently at work at this very important locality. 



The subject of tidal observations at Madeira was brought under the 

 notice of H.M. Government by the Chairman of the Committee. 



A communication has lately been received from the Foreign Office, 

 saying that H.M. Minister at Lisbon, having urged the matter upon the 

 Portuguese Government, " has received the assurance that it will gladly 

 adopt the suggestion of the British Association and establish a tidal gauge 

 at Funchal." 



In consequence of the results of the tidal observations already under- 

 taken not being iu a sufficiently advanced state for presentation at this 

 meeting, the Committee request to be reappointed, and also that .£10 be 

 placed at their disposal.

Board of Trade, (Harbour Department), 

 Whitehall Gardens, S.W., July 11th, 1878. 



Sir, — With reference to a letter, dated the 31st May last, addressed 

 to this department by Sir William Thomson, LL.D., in his capacity of 

 Chairman of the Committee of the British Association, " on Tidal Observa- 

 tions in the English Channel, &c," calling attention to the want of a 

 tide gauge at Dover, and enquiring whether the Board of Trade would be 

 disposed to undertake the expense of placing a continuous self-recording 

 instrument at the Government pier, where there is already a tide- well, I 

 am directed to acquaint you that this Board have received the sanc- 

 tion of the Lords Commissioners of Her Majesty's Treasury to the 

 expenditure for this purpose of a sum not exceeding one hundred and five 

 pounds (£105) (the estimated cost as given by Sir W. Thomson), and I 

 am to state that your Committee are at liberty to take the necessary 

 steps for fixing the gauge. 



I am to add that Mr. Druce, the Resident Engineer and Officer of 

 this Board at Dover, has been instructed to give such facilities in the 

 matter as he is able to afford. 



I am, Sir, . 



Your obedient servant, 



C. Cecil Teevoe.
