2 REPORT ON TWO BOTANICAL COLLECTIONS FROM 



In 1894 the journey to Roraima commenced (October 16) at Kwaimatta, a village on 

 the open savannah to the south-east in latitude 3° 50' N. The Ireng was crossed at the 

 Karona Falls, the Kotinga at Sokoking, a ford not named on the older maps, but situated 

 a little to the south of the meeting of the Kotinga and Karakanang streams. Thence 

 the way led into the Arabapu Valley (November 3), on the north and west sides of which 

 rise the slopes of Roraima. The return journey was commenced on November 11, and 

 the route taken crossed the Kotinga nearer its source at Orinidoui (apparently the 

 " Orinidouk " of the old maps), and the Ireng again at the Karona Falls. 



In 1898 the journey was commenced (August 20) on the lower Mazaruni River. The 

 great bend of this river, where the Peaiman Falls occur, was avoided by a porterage 

 from the Kurubung Creek to the upper Mazaruni, which was again left by the Kako 

 River; the Kako was paddled up until a point was reached about twenty miles north-east 

 of Roraima, and thence, leaving the canoes, a track through dense forest was taken until, 

 in the second week of October, the south-eastern face of the mountain was reached. 

 Roraima was left again at the end of October, and the way retraced to the lower 

 Mazaruni. 



Three days in 1894, nine in 1898, were spent in making collections upon the broken 

 plateau which forms the summit of Roraima.
