The main object of the University expedition of 1911 into the vine ridge
and sandhill regions of Nebraska was a study of ecological conditions. As a.
meens to this end, three hygro-thermogrephs vere carried, and in each region —
stucied, these instruments, after as careful adjustment as possible to insure’
ecomnar sie records, were set out in selected places, chosen with a view to ©
showing the extremes of temperature ond humidity of the given region. The
temperature record would proceed automatically, but an adjustment of the yen
recording humidity, based on a local psychrometrie test, was necessary when-
ever an instrument was set out. With these records es a basis, it is hoped
that a study of the life and life conditions in the vicinity of each station
will afford a better understanding of various problems of distribution, and
the relation of the fauna and flora of one region to those of neighboring but
very different regions. Owing partly to lack of familiarity with these new
may uments , end owing partly to a mechanical Lore which it is hoped the man
tion of the trip. On some occasions the ink failed to flow and the records —
were illegible; in other cases the pen recording temperature and that record-
ing humidity caught when they reached a point of coincidence and failed to
give a true record until released. But generally the instruments made a fin
record, and it is hoped that future work with them will be satisfactory ae
throughout instead of intermittently. Portions of the summer's data in thi
respect, then, are worthless, but as records for several seasons will be
