A 
covered woods end fields. the clay was cloudy and th® dreariness accent- 
uated by the somber landscape on all aides. I mmm end walls ware covered 
by ash like dirty snow. Froa this direction two columns of make were diet- 
east ond one froa the 
test* one froa the/ west edge of the crater, th© eastern one emitting thin 
awoke and some rooks, the western one a dense gray dust column. This con- 
tinued wit 11 min clouds drifted in froa the rwwt end eheenred the eon©. 
In the afternoon the rain ceased for & while and while planting tubas 
in some fuaaroles aloJg the north front of the old. lava, we found a new ridge 
of oxidized ash, formed, presumably the previous night, extending from the 
southeast and about ten meters high. Farther to the west, between two low 
hummocks for ash covered lava, on® could am a small patch of rugged lava. 
This proved to be a new flow, issuing froa beneath the ash ridge near the 
bass of the cone, and flowing to th© northwest to the orilla of Paricntin. 
It had already progressed several hundred asters and judging froa its rate 
of flow, had probably broken out about ald-norning. 
As it flowed down the steep orilla . its front become steeper and higher, 
until its slops exceeded th© angle of repose of the loose black surface 
blocks, when the flowing front was completely base and we could observe 
from within s very short distance the mm r of flow. The advance of the 
viscous lava took pise© as slowly bulging lobes, giving the front a gross 
bo t ryot dal surface, bulging and cracking like rising dough, the lower and 
principal lobe slowly folding under, incorporating within itself the loose 
blocks at th© foot of the flow. As the bulges developed, they finally over- 
came bhe viscosity of the lava «nd masses of semi-plastic lava would tear 
slowly off and fall to the foot of the flow. The flow gave off sparse blue 
vapors but no odor, and the only sound of the moving lava was the clink of
