five days spent in coining up. Our return 

 route therefore followed the S.W. ridge, 

 leaving the spur by which we had ap- 

 proached it from the Momi to the right. 

 Continuing due north we gradually de- 

 scended to about 5000', then bearing east 

 along a lateral spur which finally dipped 

 very steeply to the rocky bed of a tribu- 

 tary of the Moini. After crossing the 

 latter, we emerged on to the north bank 

 of the Momi River, whore we bivouacked 

 for that night, returning to Wariap the 

 next day. 



The chief difficulty of this somewhat 

 strenuous route is the want of water, 

 there being none between the vicinity of 

 the lakes and the tributary of the Momi. 



According to fig. 2 this route would 

 follow the " Bonyas Gebebergte," which 

 join the spurs of the Arfak indicated on 

 the sketch-map to the north of the sup- 

 positional position of the Ransiki River. 



The altitudes in the sketch-map, 

 judging by the character of the vege- 

 tation, seem somewhat underestimated. 



2. METEOROLOGY. 



The following facts referring to the 

 north-west coast are taken from Braak's 

 (24, 210) paper on the climate of New 

 Guinea, which summarizes all the infor- 

 mation at present available. 



On the north coast the east or dry 

 monsun prevails from May and June to 

 September and October, though even 

 then much rain may fall. In Mano- 

 koeari the east monsun is the driest time 

 (24, 219). It is probable that in the 

 interior the difference between the cha- 

 racter of the E. and W. monsun is much 

 less pronounced. 



In N. New Guinea it is at present 

 not possible to give actual figures, though
