THE SCIENTIST. 
This last assumption accounts for the 
fact that the sinus or trough is so much 
narrower between Pueblo and Canon 
City than it is east of Denver, i. e., 
further north. At the one place it is 
seventy-six miles from ridge to trough, 
at the other the farther south, it is forty- 
two miles between ridge and trough. 
Just south of the Arkansas river at 
Pueblo the mountains swoop around, 
trend, more in an easterly direction. As 
this glacier moved south across the river 
it came in contact with the mountains 
and was probably about melted and 
otherwise annihilated by the time it 
reached Trinidad and the eastern arm of 
the Katton mountains. It is possible 
that the overflow of it passed through 
Cimarron Pass further to the st-uth-east 
and found vent on the plains of the 
Pecos in eastern New Mexico. To sum 
up then, the drift of Colorado is probable 
true glacial, while the drift of New 
Mexico is postglacial, overflow from the 
glaciers farther north. The drift I ob- 
served, the breccia, in New Mexico, in- 
cluding that on the Journado del Muerro 
(Hoor-nah-do del Moo-ar-to) is overflow 
that came down the Rio Grande from the 
west slope of the Sangre de Christo and 
Ratton mountains. The Journado del 
Muerto lies between the Rio Grande on 
the west and the Pecos on the east. It 
reaches from near San Marcial (Mar-she- 
el) on the noi-th, to Rincon on the south. 
It is about ninety by seventy miles in ex- 
tent. It lies from 5,000 to 6,000 feet 
above sea level. 
About all the drift on the plains, above 
described in eastern Colorado, lies at 
about the same level. The highest drift I 
observed was between Buena Vista and 
Leadville near the north end of North 
Park. Here it has an elevation of about 
8,500 feet. The drift is very abundant 
in all of the parks or high valleys of 
Colorado. It is scarce along the gulches 
and canons, in fact generally absent. 1 
remarked this in Platte canon. The 
reason for this is that the gulches and 
canons aff"orded such contracted outlets 
for the waters during the glacial and post 
glacial epochs, that all drift materials 
were brought in direct contact with the 
rushing waters and the current s being so 
swift they were carried to the plains and 
mesas below. This fact accounts 
for the absence of drift materials 
lor so many miles along the upper North 
and South Platte rivers and its abundance 
along these streams after they leave the 
mountains. At no part of their upper 
course are they above the elevation, at 
which I observed the drift in North and 
South Parks and elsewhere in wide 
valleys. Notwithstanding drift is so 
abundant in the two parks drained by the 
Arkansas river, referred to in the first of 
these notes, there is none along the forty 
miles of the river where it passes throngh 
the Grand Canon. Yet, it is very 
abundant below the canon, near Canon 
City, as stated above. 
At some future time 1 hope to call your 
attention to some of the natural resources 
of Colorado and New Mexico and 
possibly of Arizona.

That cats object to being dosed with 
medicine is a well known fact. Yet 
medicine can be administered to the 
most stubborn cat by mixing it with 
lard and rubbing the mixture on pussy's 
sides. 
Prof. Holden of the Lick observatory 
is said to have discovered on the moon 
parallel walls 200 feet thick on the top, 
and about 1,200 feet apart. 
A local editor was recently shocked 
on learning that the Lark was not after 
all the highest flyer. Humboldt's credit- 
ing the Condor with soaring 20,000 feet 
above the level of the sea was news to 
him.
