any such modifications, shall be considered an integral part of this 

 Convention. 



4. Each Party agrees to provide the Commission annually with 

 information on : 



(a) number of black pups tagged for each breeding area ; 



(b) number of fur seals, by sex and estimated age, taken at sea 

 and on each breeding area ; and 



( c) tagged seals recovered on land and at sea ; 



and, so far as is practicable, other information pertinent to scientific 

 research which the Commission may request. 



6. The Parties further agree to provide for the exchange of scientific 

 personnel; each such exchange shall be subject to mutual consent of 

 the Parties directly concerned. 



6. The Parties agree to use for the scientific pelagic research pro- 

 vided for in this Article only government-owned or government- 

 chartered vessels operating under strict control of their respective 

 authorities. Each Party shall communicate to the other Parties the 

 names and descriptions of vessels which are to be used for pelagic 

 research. 



Article III 



In order to realize the purposes of the Convention, including the 

 carrying out of the coordinated and cooperative research, each Party 

 agrees to prohibit pelagic sealing, except as provided in Article II, 

 paragraph 3 and the Schedule, in the Pacific Ocean north of the 30th 

 parallel of north latitude including the seas of Bering, Okhotsk, and 

 Japan by any person or vessel subject to its jurisdiction. 



Article IV 



1. Each Party shall bear the expense of its own research. Title to 

 sealskins taken during the research shall vest in the Party conducting 

 such research. 



2. If the total number of seals of the Commander Islands breeding 

 grounds decreases and falls below 50,000 head, according to data in 

 official records, then commercial killing of seals and apportionment of 

 skins may be suspended by the Union of Soviet Socialist Republics 

 until the number of seals exceeds 50,000 head. This provision also 

 applies to the fur seal herd of Robben Island, if the population of that 

 herd becomes less than 50,000 head. 



3. The Government of the Union of Soviet Socialist Republics upon 

 suspending such sealing shall so inform the other Parties. In this 

 case the Commission shall determine whether or not to reduce the level 

 of or to suspend completely the pelagic sealing for scientific purposes 

 in the Western Pacific Ocean during the period of the said suspension. 



4. The Commission may, subsequent to the second year of operation 

 of the Convention, modify the floor figure set forth in paragraph 2 

 of this Article in accordance with its findings based upon scientific data 

 received by it ; and if any such modifications are made, paragraph 2 of 

 this Article shall be considered amended accordingly. The Commis-
