RECENT WORK OF PROF. HAYDEN.
SUPPLEMENTARY TO TRIBUNE ACCOUNTS OF ExPLoR-
TIN

ING EXPEDITIONS AT THE WEST.
Prof. Hayden appeared before the Academy to
give general account of the scientific explorations
and survey at the West in which he has been en-
gagged As full accounts Of these explorations have
appeared in The TRIBUNE it will be unnecessary to
reproduce the details with which our readers are
already familiar The following particulars are
concerning more recent work and bring the story OF
these explorations from the accounts in THE IRIB-
UNE Extra OF Dec SOth to the present time.

Prof Henry said that we are inviting thousands
of foreigners to come here and ought to be able
TO tell them what we have to offer them. For this
purpose survey Of the whole United States ought
| To be made We have three organizations for this
nurpose-the Coast Survey, the Engineers Survey,
and this Civilians Survey. 1t is very desirable that
there should be no wrangling between these organi-
zations that their work be brought into coordina-
| tion and unity He recommended that the Academy
| take this matter into consideration, ana perhaps
| suggest the formation OF commission, 49,
| Prof J. Lawrence Smith OF Louisville Kentucky,
followed up this observation with one on the lack OF
unity in the State surveys. His own State suffered
| much from the need of correct surveys from h&el
| noints determined by the Coast Survey 1t IS eX-
cccdingly desirable that the method and system OF
all SURVEYS be placed under one head and conducted
with uniformity.
Col. Forshay of Louisiana enforced the foregoing
| views by his experience In that state ana TGmaiKeu
! also on the value and interest OF Prof llaydens
work In the matter OF hydrOgraphlt surveys there
was almost an equal deficiency OF unity OF plan and
| useful results.
| Gen. Barnard of Washington referred to the ex-
IRENE difficulty that was found in conducting tho
operations OF the war without maps of a topograph-
| zeal character He considered that much or the
DELAY which characterized our undertakings IN the
| war was principally due to our ignorance OF tue
