sorted deposits. 'J'liese moraines* are at tiie eonflnence of tlie 
three rivers. Se<rovia. Depilto and Macnleso whose a<i<ireLr:»ti' 
hvdroii'raphie area is altont ei<:ht thousand s(|nare niiU's. My 
notes, made after several examinations at intervals during a stay 
in that part of Nifara<ina of aliont four months, state that possi- 
lil\ a larii'e j)oition. if not all. of these deposits are moraines. 
Several hirjie knolls and small hills are fouiul north of the vil- 
hige of San Rafael del Norte, in the department of Matagalpa. at 
the southwestern foot of the Cerro Valli. aliout lat. \?>° 20' N. 
and lonu". S(»° \\ . . t'arh havinji' extensions of from one hun(h'ed

Itafael del Norte, composed, so far as my I'xaminat ions exteiKh'd. 
of the unassorted, unstratilied fra<inients of rocks :ind pehliles. 
some rouiih. otiiers smooth-ed<>;ed: all embedded in sands and 
ehivs. In some [ilaci's the clays, in others the sands are in excess. 
These deposits were first discovered l»y the late Thomas Belt. V. 
1\. S.. and described in tlu* second edition of his -Naturalist in 
Nicarajiua. piililished within the past few years in London, lie 
di'clares them to be moraines, which if discovered in Canada 
would uiKpiestionably be so considen'd. Cerro Yalli. at this 
localitv. is tall and has stee|) sides, but the liydrooi-Mphic area is 
coiiii)aratively larti"e. and althou<>"h I found no narrow, deep ra- 
vines in the si(U' of the mountain near these jilei)osits of nn- 
T believe it was his only trip (and one of ordy a few daj'S) totliis h^x-alitv, 
distant for more than tliree or four Icai^ues, from tlie mines near 
l>abibertad (that lie superintended for a few years I. lie was a quick 
and close observer, but was hurried on this trip and did not note, prob- 
ably, the lariie hydroiirai)hic area of the tliree rivers. Se.i;ovia, ^Macnleso 
and Depilto which unite, in this locality, their rapid currents. 
*I had doubts about these beinj; moraines, until two months a>io, when 
for the first time and only for a few hours, I had opportunity to exam- 
ine the work of the late Thomas Belt, referred to in foregoing note. 
I believe Mr. Belt was correct in desiguatuig these deposits moraines. 
.My doubts occurred because we are sometimes lial)Ie to mistake de- 
l)nsits made by water for those made by ice, unless after extensive ex- 
cavations, etc.: also, Iiecause tiie water-slied of these three rapid rivers 
is ipiite large, and in flood times they transport large Itoulders for loilg 
distances, and, because there are evidences that a part, if not all, of that 
vallev has been overflowed.
