respect to their alleged depletion, the causes which may have lead to
their impoverishment, and the means by which they might be con-
served and their productiveness increased. As a result of the scien-
tific and statistical investigations, the Commissioner soon determined
that certain fishes had decreased, and was able to recommend an efh-
cient means for bringing about an increase or at least arresting fur-
ther depletion. This was to be accomplished through the agency of
fish culture, and little time was lost in securing for the project the
sanction of Congress by an appropriation.

In 1872 a few salmon and shad were hatched and planted, and by
1880 eight species of fishes, including three kinds of salmon, two
trouts, shad, whitefish, and carp, were being produced on a compara-
tively large scale and active experiments were being conducted to
determine the methods best suited for other species.

This phase of the Bureau’s work has now grown to enormous pro-
portions, and in the fiscal year ended June 30, 1915, 49 species were
prepagated, these including, in addition to fishes, the lobster and
several species of economically valuable fresh-water mussels. The
total product of these was over four and a half billion eggs and
young, which were planted in every State and Alaska. Some idea of
the magnitude of the work of distributing these is indicated by the
fact that it involved 637,716 miles of travel, of which 146,544 was by
the Bureau’s special cars and the rest by messengers. These marine
and fresh-water fish and invertebrates were collected and hatched by
40 stations and 95 substations located in 34 States and Alaska. In
addition 8,404,000 food and game fishes were rescued from overflowed
lands, where they were in peril of being left by the receding waters,
and returned to the safety of the streams.

Solely by reason of these fish-cultural operations and similar actiy-
ities on the part of the States, the supply of trout and other game
and food fishes in streams and small lakes is being maintained and
increased, the whitefish of the Great Lakes is holding its own, the
shad in certain waters is being saved from extinction, and the effects ©
of heavy fisheries for the Pacific salmons and certain marine fishes
are being compensated. As a result of transplanting, the Atlantic
shad and striped bass are abundant on the Pacific coast, and the
former are being shipped back in large numbers to supply the mar-
kets of their ancestral regions. Certain depleted salmon rivers of
Maine recently have been planted with humpback salmon fry from
the Pacific coast and small runs of breeding fish already have

appeared in several of those streams, raising the hope that the nearly
exterminated Atlantic salmon may be replaced by a worthy successor,
better able to cope with the conditions established by the settlement
of the country. It is believed that. the recentiy inaugurated propaga-

tion of fresh-water mussels will relieve the prospect of a depletion of
the supply of raw material for the pearl-button industry.

The statistical work inaugurated as a necessary part of the original
functions of the Bureau has been continued and enlarged. Period-
ical canvasses are made of the fisheries, usually by geographical

regions, e. g., New England States, Middle Atlantic States, South
Atlantic States, Gulf States, Pacific Coast States, Mississippi River
and tributaries, Great Lakes, minor interior waters, and Alaska. In
the last few years unusually comprehensive statistical reports have
been published on the oyster, menhaden, lobster, and fresh-water
mussels. This statistical information is not only of immediate in-
terest to the fishery industries, but is highly important as a basis for
determining the necessity and the measures for the regulation and
conservation of the fisheries.

The regulation of the fisheries, whether in navigable waters or not,
is a function of the government of the several, States within which
they are located, and until recently the Bureau of Fisheries had no
executive duties in the enforcement of fishery regulations, although
through its advisory capacity exercising large influence over fishery
legislation. It is now charged, however, with the enforcement of the
laws relating to the fisheries and the taking of fur-bearing animals in
Alaska, and has entire administrative control of the Pribilof Islands,
their native inhabitants, and the fur-seal herds which resort to them
during the breeding season. The annual value of the fishery products
of Alaska is about $20,000,000, or over two and one-half times the
original cost of the Territory to the United States.

The scientific work for which the Bureau was originally created
has grown greatly in both quantity and scope. It embraces the study
of the habits, distribution, diseases, and classification of fishes and
other aquatic animals, especially those of commercial importance, and
of their food and enemies. As any organism is controlled more or
less by its environment, the study of a commercial species involves
investigation of the other animals and plants with which it is directly
or indirectly associated and of the physical and chemical characters
of the waters in which it lives. The information necessary as a basis
for the conservation and improvement of the fisheries, therefore,
covers a wide field in aquatic biology, physics, and chemistry, and
the scientific work of the Bureau is governed by an appreciation of
these requirements.

The results of investigations are not always susceptible of imme-
diate practical application, and to make them commercially valu-
able a considerable part of the Bureau’s work consists of expert-
ments to develop methods by which they can be applied to the needs
of humanity.

4 BUREAU OF FISHERIES.

Investigations and experiments are conducted by “ field parties”
working in all parts of the country, at the general laboratory in
Washington, the marine biological stations at Woods Hole, Mass.,
and Beaufort, N. C., and the biological station on the Mississippi
River at Fairport, Iowa. For marine investigations the Bureau has
an able seagoing steamer, a coastwise steamer, and a fishing schooner
with auxiliary gasoline engine power, and various launches and small
boats are employed both on the coast and in interior waters. In
addition to the small permanent scientific force, which is inadequate
to meet the demands, the Bureau employs temporarily a large num-
ber of qualified investigators and assistants connected with universi-
ties, colleges, and other institutions of learning. Some of the practi-
cal scientific aid which the Bureau has extended to the fisheries in
recent years consists of the location of new fishing grounds, the
development of markets, and means of using wasted or neglected
fishery resources, the development of methods of sponge, terrapin,
and fresh-water mussel culture, causes of disease in fishes, surveys
of oyster bottoms and recommendations for their conservation and
utilization, recommendations for State fishery legislation, etc.

The results of the work of the Bureau are published in two series,
the “Reports,” of which there are 40, and the “Bulletins,” of which
39 bound volumes have been issued to 1915. <A recently established
series of “ Economic circulars” gives prompt information on sub-
jects of economic interest. These and pamphlet separates of the
papers included in the reports and bulletins are furnished to inter-
ested persons on application to the office of the Bureau, Washington,
D. C. Mention of some of the work recorded in these papers is
made in the following account of the equipment, functions, and
accomplishments of the biological station at Beaufort.

The coast of North Carolina, with its rivers, its great salt, brack-
ish, and fresh-water sounds, its sea shores, bights, and offshore
banks, has long been noted for its fisheries. It is recorded of the
Indian Chief Manteo that, after his visit to the ships of Sir Walter —
Raleigh’s colony on Roanoke Island in July, 1584, he “ fell to fishing,
and in less than half an hour he had laden his boat as deep as it
could swim.” First the early explorers and later fishermen and
naturalists have been attracted to the coastal region of North Caro-
lina by the wealth of aquatic lfe—fish, oysters, clams, scallops,
crabs, shrimp, terrapin, porpoises, seaweeds, and a host of living
things which have no names other than those which science has given
them.

Following the visits of the zoologists, Gill and Stimpson, in 1860,
and Coues and Yarrow, in 1871-72, Beaufort became a resort for
persons interested in biology, and for a period of 10 years some of

the professors and students cf Johns Hopkins University main-
tained a laboratory here. Prof. Baird and cthers connected with
the Bureau of Fisheries investigated the fishes of the region within
the first decade of the Bureau’s existence, but it was not until June 1,
1899, that a fisheries laboratory was established. This was in a
rented building, but in 1900 Congress authorized the erection of a
biological station, and on May 26, 1902, the present building was
thrown open for research. Situated in a region in which fishing
is a leading industry and where a considerable part of the popula-
tion is largely or entirely dependent on the fisheries for a livelihood,
the laboratory was established with the primary purpose of furnish-
ing aid to that industry. Therefore, while scientific investigation

tion and development, to discover the laws and the facts which fur-
nish the foundation for “ practical” work, the laboratory does not
stop with pure research but endeavors to make concrete application
of the results.

THE STATION AND ITS EQUIPMENT.

The station is situated on Pivers Island, with an area of about 4
acres, about 150 yards west of the city of Beaufort. The plant con-
sists of the laboratory building, a mess house and kitchen, power
house and pumping plant, carpenter shop, boathouse and ways, anda

and shrubbery and the more exposed shores are protected from ero-
sion by sea walls of concrete and heavy granite bowlders.

The laboratory building is a two-story frame structure, 70 feet long
and 42 feet wide, with 2 two-story wings each about 52 feet long
and 18 feet wide. The wings are occupied by six bedrooms each, for
the accommodation of the enlarged scientific staff employed during
the summer, while the central portion of the building is devoted to
purposes of investigation, instruction, and administration. The
laboratory occupies the entire second story, removed from the dis-
tractions and noises inseparable from those parts of the buildings

walls are alcoves for investigators, separated by half-height. parti-
tions, designed to interfere as little as possible with the free passage
of light and air. Each is provided with a table and shelving and
whatever aquaria, dishes, apparatus, and reagents may be required
for the particular work in progress, and one or two high windows
furnish light and ventilation.

Near each end of the laboratory are two large tank tables, with
aquaria, affording facilities for keeping and observing the live plants
and animals brought in from the waters of the harbor. Chemical
reagents and other frequently needed supplies are kept in two long

locker tables conveniently placed in the center of the room, but the
more bulky and fragile glassware and special apparatus is stored in
the supply room on the first floor and issued as required. Sinks, a
fume chamber, and a photographic dark room are located along the
end walls of the room.

The museum occupies the first floor and is open to the public. It
contains many animals and plants representative of the marine fauna
and flora of Beaufort Harbor and its vicinity,.and will prove of
interest to the casual visitor, but particularly to those who fish or who
explore the beach for the spoils thrown up by the waves. The speci-
mens at present (1916) in the museum were preserved primarily for

the use of investigators, but it is hoped eventually to have a specially
prepared exhibit of greater interest and educational value to the
general public. The tidal boxes and aquaria along the walls of the
museum are intended for this purpose and are generally stocked with
living organisms brought in by the collectors who daily scour the
harbor and the shores in search of specimens.

The library is in a room at one end of the museum and contains
about 1,000 volumes. While small, it has been selected with special
reference to the needs of the investigators, who also may obtain books
from the excellent main library of the Bureau in Washington and
from the other unusually rich public libraries of that city.

The three other rooms corresponding to the library are used for
offices, supplies, and special scientific purposes, respectively.

The laboratory building, as befits its needs, is abundantly supplied
with both fresh and salt water. The former is derived from an
artesian well, the flow of which varies with the tides, while the salt
water 1s pumped from the harbor. The buildings and grounds are
lighted by electricity carried by submarine cable from the city lght-
ing plant.

There are attached to the station 2 launches, 26 feet and 33 feet
long, respectively, and about 15 rowboats, which are used in making
collections, and for special offshore investigations the Fisheries
steamer ish awh is detailed as required. There is an ample equip-

various types of tow nets and dredges.

The radio station is a separate establishment operated by the Navy
Department by courtesy of the Department of Commerce.

THE WORK OF THE STATION.

The laboratory concerns itself mainly with two interdependent
lines of work. In the first place it aims to conduct scientific mvesti-
gations to determine not only the life histories of aquatic forms of
economic importance, but also “the histories of the animals and_

BIOLOGICAL STATION AT BEAUFORT, N. C. 9

plants upon which they feed or upon which their food is nourished ;
the histories of their enemies and friends, and the friends and foes
of their enemies and friends, as well as the currents, temperatures,
and other physical phenomena of the waters in relation to migration,
reproduction, and growth.” In the second place it strives to show
~ how the knowledge thus gained may be applied to maintain our more
important fishery industries against deterioration and to reestablish
those already depleted by natural means or by perfecting methods
for supplanting or replenishing natural stock with that grown under
more or less artificial conditions, bearing the financial burden in
experimental methods of scientific aquiculture and in the search for
undeveloped or unknown fisheries.

Diamond-back terrapin pound.

A review of what has been accomplished at the station is 1mpos-
sible in this brief paper. Reference to several investigations, illus-
trating something of the diversity of the station’s work, may prove
of interest. One of the first was a report on investigations for the
promotion of the oyster industry of North Carolina. Attention was
called to the ways in which natural oyster reefs were formed under
the conditions prevailing in this region; to the factors which one
engaging in “oyster gardening” must consider; to the misfortunes
and successes of some of those who had attempted oyster farming;
and, by experimental oyster planting, to the fitness or unfitness of
certain bottoms to oyster culture. When the State awakens to the
need of encouraging its citizens to engage in this industry and

supplies the machinery for properly protecting oyster farms, this
information will be in demand.

One of the investigators made a report on the vegetation of Shack-
leford Banks, calling attention to the changes which these banks have
undergone from a region of forests reaching nearly to the water’s
edge on the seaward side, to one of barren desolation in which not
even the huts of the fishermen are safe; and in several instances they
have had to be abandoned and new sites sought. Means of establish-
ing barrier drives, of reforesting the region, and the value of various
plants as sand binders, etc., are discussed.

The work of the Fisheries steamer Fish Hawk in locating and
charting some offshore blackfish grounds opens up new possibilities
of special interest to local fishermen at a time when several of their
important fisheries are at a low ebb. The largest bank, lying about
21 miles southwest of the bell buoy on Beaufort Bar is at least 7
miles long by about 24 miles wide. To enable fishermen to find it
with greater ease, a first-class can buoy has been planted near its cen-
ter by the Bureau of Fisheries.

One of the most unique and important constructive investigations
has been the development of the artificial propagation of diamond-
back terrapin whereby the cultural methods perfected at the labora-
tory may be duplicated and applied to the cultivation of terrapin as
a commercial enterprise. With the development of the regions which
the diamond-back inhabits, it will be increasingly difficult to main-
tain a natural supply. There is reason to believe that the commercial
culturist may greatly increase the supply and cheapen the product.

The station’s plant affords a practical demonstration of working
methods. Here, one seriously contemplating engaging in the industry
may observe how the breeders, the eggs, and the young are cared for.
Many problems of a practical nature as rate of growth, winter feed-
ing to shorten the time of reaching a marketable size, etc., are being
prosecuted. In its pens are terrapin hatched in the laying beds
ranging in age from those just hatched to those 5 years old. The
older brocds have reached maturity and their progeny are being
reared for comparison with their parents and the wild stock.

In cooperation with the Forest Service of the Department of Agri-
culture, studies of the shipworm and other marine borers have been
conducted for several years with the ultimate object of determining
how the damage to shipping, bridges, and wharves wrought by these
destructive animals may be controlled and minimized. This is a
problem of great interest to shipowners and engineers, but for which
no satisfactory solution has been offered.

From the time the laboratory was first established to the present,
the collection of information on the food, breeding, migrations, and

BIOLOGICAL STATION AT BEAUFORT, N. C. 11

life histories of the fishes of the region has been an important part of
the work, until, with the possible exception of the vicinity of the
Bureau’s laboratory at Woods Hole, the knowledge of these matters
is more complete than for any other locality on the Atlantic coast.
About 260 species of fishes are known from Beaufort and its vicinity.
Experiments are now being conducted to determine if some of the
principal food fishes can be artificially propagated to advantage.

While the chief aim is to render service to the fisheries, sight is
never lost of the opportunity to carry on more abstract researches, .
and particularly to extend to volunteer investigators the facilities
which the location and equipment of the laboratory afford. The pub-
lications in pure and applied science which have issued from the
station cover a wide range and many titles.
