nortli-wosl, against the lillle viuv^a i-adialiiiü,' from the Soput'laii-cuiic 

 the circumference of the mass of stones adapts itself more to the 

 level-lines than the sketch on the map indicates, and tluit the Pentoe- 

 hed on detailed surveying would prove to be more submerged; in 

 this way the otherwise rather |)u///.ling streain-sha[)ed extremity near 

 the solfalare of HIOl will probably have to be amended. 1 have 

 however found no freedom to depart from Dr. Sciiocn's indications. 



If at any time a "Nachscdiub" of great im|)()rtance is coming on, 

 then firstly the remaining part of the ali-io will be (illed, and then 

 a stream of blocks will go down into the Pentoe-ravine. The similarity 

 with Roeang would then, or even now if the quantity of the new 

 material had been greatei', be readily perceptible. Another stream might 

 spread itself then in tiie grit-tlelds between S()i)oelan and iManimporok 

 running down southward to Tombatoe. With volcanoes however, and 

 especially here, it is to be kept in mind that : "le vraisemblable 

 c'est rimprévu", and it might very well happen that in that case 

 the cinder-hearth would seek its outlet in the i-ing-wall of Sempoe 

 and then streams of blocks would take the way of Masem or the 

 direction towards Kelelondei. 



Later reports are still wanting; we may assume that since Septendjer 

 1906 cone 4 has gradually ceased to smoke, which was in fact the 

 only after-etfecl. Not until 5''' or 7''' of June 1907 a new activity is 

 rejHjrted, (Nat. Tijdschr. v. N. I. Dl. LXVIII p. i 20) with a violence 

 "similar to that of the year before", (A. Limhurcj) ; from the crater 

 that was then formed, — unfortunately it does not ap[)ear which of 

 the two crater-cones is meant, — "dense colunms of smoke emerged, 

 and at night a glare of lire was percei)tible"\ (Controller of Amoerang). 

 A great "Nachschub" did not occur then ; this appears from what 

 has been said. Pi-esumably even little or no material has been 

 ejected, otherwise the solfatare of 1901 would most likely hax'e 

 become pai'tly or entirely choked, and this would soon have been 

 perceived. The statement of the controller of Tondano, that on 25"' of 

 June after the earth-(piake of that day \^ increased act i\ ity of .Soj)oef an 

 could be observed, makes us suppose that at that time the acti\it\- 

 had ali'cady i)een abating again. Passing and without lasting conse- 

 (piences as the phenomena of that ycai' e\idenlly were, they ai"e 

 however in my opinion of importance as a [)roof that the activity
