‘The attached Calhoun forms contain data which have not been used in
the calculations of any census information. Bad weather is assumed to
have biased the sampling. Animals recorded have been processed for
future study on food habits, etc., and they are enclosed with all the
other preserved specimens of the 1972 Calhoun line census.’ –H.A.

Trapline U:
<emphasis role="strong">Records not labled. Line not

. Titled U for Unknown. Possibly Line I. The
folder containing the hardcopies was originally labeled “1958-63

(Written in a variety of scripts.) A few forms were not entered into
database due to inability to decipher short-hand, lack of date,
repetition of date, questions as to placement, and possible repetition
of information. Please consult hardcopies.

‘ I am assuming that all Tamias collected here in 1984 are T. amoenus
as all had yellow mid section of dorsal tail hairs. This character is
what Jim Pathr said to use to separate T. amoenus from T. speciosus
(orangish mid section).’

‘ Dick Gard:
Calhoun Line 1000 feet long, 21 stations, 50 feet apart, 3 traps at
each station. Each within 5 feet of stake at likely spots. Use either
live or snap traps but be consistent. Run 3 day consecutively,
checking morning and night. Numbers of various species or sexes caught
do not necessarily indicate relative abundance as some come from
longer distances to the traps (male, male and larger mice).

Trapline M:
<emphasis role="strong">1965 Note:</emphasis>
June 30 to July 2, 1965 (Francis Milno?)
'Trap line number VII (M) was laid out in the meadow across the stream
from the Sagehen Creek Station. There are 21 stations in a straight
line, spaced 50 feet apart for a distance of 1000 ft. At the central
station, station eleven, the line is at an angle of 310 degrees with
line drawn to the station flag pole.'
<emphasis role="strong">Description of Station and catch for each
Station</emphasis>
'Caught 3 microtus (all durring day) and 8 peromyscus, all at night.
Night temps went to lows between 30 and 40 degrees F all three nights.
Former years show higher catch of microtus. 'The microtus catch is
quite low this year. Since microtus are supposed to be easy to catch,
there appears to be a low microtus population. The data for the year
shows a scattering of microtus and peromyscus too scarcely to draw any
good conclusion. The data is far too poor to attempt to estimate the
total microtus population. One thing it suggests, however, is a
difference in activity between the two species of mouse; the
peromyscus being caught at night and microtus durring the day.'
<emphasis role="strong">Note 7/25/65- 4:30PM.:</emphasis>
'It rained the evening before and this afternoon. Every trap was
sprung.'
<emphasis role="strong">Note 1984:</emphasis>
'Note: I believe the recorded Sorex trowbridgii should all be Sorex
vagrans as tail is distinctly within the range of S. vagrans (38-46mm)
not sorex trowbridgii (51-64mm) which has a longer tail. Second
measurement is tail length. Also, this habitat (meadow) is typcially
S. vagrans type, not that of S. trowbridgii (forest floor).
