60 APPENDIX TO BRITISH CASE. 



The commissioners so named shall meet at London at the earliest 

 convenient period after they shall have been respectively named, and 

 shall, before proceeding to any business, make and subscribe a solemn 

 declaration that they will impartially and carefully examine and 

 decide, to the best of their judgment, and acording to justice and 

 equity, without fear, favor, or aifection to their own country, upon 

 all such claims as shall be laid before them on the part of the govern- 

 ments of Her Britannic Majesty and of the United States, respec- 

 tively; and such declaration shall be entered on the record of their 

 proceedings. 



The commissioners shall then, and before proceeding to any other 

 business, name some third person to act as an arbitrator or umpire 

 in any case or cases on which they may themselves differ in opinion. 

 If they should not be able to agree upon the name of such third per- 

 son, they shall each name a person; and in each and every case in 

 which the commisioners may differ in opinion as to the decision which 

 they ought to give, it shall be determined by lot which of the two 

 persons so named shall be the arbitrator or umpire in that particular 

 case. The person or persons so to be chosen to be arbitrator or umpire 

 shall, before proceeding to act as such in any case, make and subscribe 

 a solemn declaration, in a form similar to that which shall already 

 have been made and subscribed by the commissioners, which shall be 

 entered on the record of their proceedings. In the event of the death, 

 absence, or incapacity of such person or persons, or of his or their 

 omitting, or declining, or ceasing to act as such arbitrator or umpire, 

 another and different person shall be named as aforesaid to act as 

 such arbitrator or umpire in the place and stead of the person so 

 originally named as aforesaid, and shall make and subscribe such 

 declaration as aforesaid.
