502 SEA CHARTS USED IIS" THE MARSHALL ISLANDS. 



for Egedai, or distance at which the island may be seen from the canoe; 

 3-3, for the Djelladai', or distance at which palm trees ma}^ be distin- 

 guished. The line 4^, to one coming from the north, stands for the 

 Djugai of Namu Island; 5-5, for the Egedai, and 6-Q for the Djelladai. 

 In like manner on these lines the Bungdockeings and the Bungdock- 

 eriks, or northern or southern dunungs, are made plain. 



This Rebbelib, or chart, of the whole group is specially interesting, 

 because upon it are set down the meetings of the Rilibs and Kaelibs, 

 with Bungdockeings and Bungdockeriks which form the Okar leading 

 to the island sought. It also furnished the basis for all navigation. 



CHART V. 



Dimensions of the chart from P to U, 103 centimeters; from S to H, 

 128 centimeters. It is a Rebbelib, or group chart, for the Ratak 

 chain. The term Rebbelib, as it has been defined, is not applicable 

 here, since the mussels point out no definite islands of the Ratak 

 chain, but are introduced merely as examples, but the interpreters 

 held, notwithstanding, to the term Rebbelib. There scarcely exists 

 the necessity for a Rebbelib of the entire Ratak chain, since naviga- 

 tion there is onl}^ local. 



The meaning of the lines is as follows: 



AH locates a Bungdockerik; AP, an Okar, or sailing line, between 

 islands A and P; HS, an Okar between H and S; LWVU, an Okar 

 between these points. 



The curve rrrr, between H and S, is a Rilib. 



The curve kkkk, between H and S, is a Kaelib. 



The curve bn, bn, between N and V, a Bungdockeing. 



The curve bk, bk, between J and V, a Bungdockerik. 



The line EC and EF must signify the Bungdockerik for an imagi- 

 nary island at E; the lin3 KG, a Bungdockeing for the island K. 



The curve KG may point out the general course of a Bungdockerik; 

 the line BD is a Rolok for the island B; the curve MXZ, the general 

 course of a Bungdockeing, as also the line PRSTU; QO and QR fix the 

 Bungdockerik for the island Q; the unnamed lines have no special 

 meaning, the sticks serving only to hold the others together. 



NAVIGATION IN THE MARSHALL GROUP: 



The Marshall islanders are born sailors, as the position of their 

 islands would occasion, and always pushed the art of na\'igation 

 extensively. Longer journeys were speciall}' undertaken in the Ralik 

 chain, since its atolls and islands all belonged to the royal family and 

 for that reason kept up a livelier commerce with one another. Only 

 war expeditions were sailed from the Ralik to the Ratak chain. 



In the Ratak chain navigation from atoll to atoll is not so lively,
