STRATIGRAPHICAL GEOLOGY 
Regarding the term Manzano Group, which Mr. Lee applies to 
the reddish shales and sandstones lying above the main limestones 
of the Sandia and Manzano mountains, and his adaptation of 
Professor Herrick’s alleged usage of it as a geographic name, there 
seems to be decided misapprehension. Professor Herrick, as his 
various writings clearly show, never formally proposed this term 
as a specific formational title. His name “Manzano Series,” for 
instance, was distinctively a term given to any part of the rock- 
sequence exposed in the Manzano mountains. In like manner he 
had a similar title for the exposed section of every mountain 
range throughout the region. His usage of the word series surely 
was intended to carry no taxonomic significance whatever. By 
him the word series was used in the same way that Professor Ha¬ 
worth often applied the name system to small lithologic units in 
Kansas; and as most geologists use the word section, sequence, 
or succession. So the Manzano series of Herrick was merely the 
Manzano Mountain section of any geologic formation, irrespec¬ 
tive of age. 
The incongruity of Mr. Lee’s adoption of Herrick’s title Man¬ 
zano Series as a formational name for the reddish or pinkish beds 
of the Sandia-Manzano range is well shown by the fact that Pro¬ 
fessor Herrick specifically stated that the lower part has a Permian 
equivalency, the middle part is probably of Jurassic age, and the 
upper portion Triassic in age. This fact alone would prevent the 
continued usage of the term as a valid geologic title in the sense 
that Lee suggests. In the use of the term Permian, Herrick 
always had in mind the Permo-Carboniferous section of Kansas 
— the Chase-Marion beds and not the original Russian Permian 
succession. 
In the Sandia-Manzano range the term Manzano has priority 
in still another sense. As to the unity and geologic age of the 
sequence of reddish or pinkish beds exposed in the Manzano 
Mountains, and by Mr. Lee included under the title of Manzano 
group, it was fully and conclusively demonstrated nearly two 
decades ago that neither the so-called Permian Red Beds (Cimar- 
ronian series of Kansas and eastern New Mexico) nor the Triassic 
red beds are represented, but that the red beds there displayed were 
entirely of Mid-Carbonic age, and were to be correlated with the 
Oklahoman series of eastern and central Kansas — the Chase and 
Marion formations. Herrick had already published, five years
