tion (aside from those who recover spontaneously 
and are credited to the apparatus) is the one 
treated manually. 
_ Even more important is the fact, demonstrated 
now by universal experience, that when apparatus 
is known to be obtainable, it is sent for and the 
manual method neglected. Thus to-day the appa- 
ratus in public use is on the whole contributing 
very materially to decrease the saving of life.

PROTECTION GIVEN MIGRATORY BIRDS BY 
AMENDMENTS TO THE BIRD-TREATY ACT 
Tue United States Department of Agricul- 
ture announces the promulgation of amend- 
ments and additions to the Migratory Bird- 
Treaty Act Regulations effective October 25, 
1918. 4 
Hereafter the open season for black-bellied 
and golden plovers and greater and lesser yel- 
lowlegs in Texas will be from September 1 to 
December 15. Another change prescribes a 
daily bag limit of 50 sora to a person in addi- 
tion to the bag limit of not to exceed 25 for 
other rails, coots and gallinules. 
_ An amendment of Regulation No. 6 has the 
effect of removing the limitation on the num- 
ber of birds that may be transported within a 
state during the federal open season. The ex- 
port of migratory game birds is limited to two 
days’ bag limit during any one calendar week 
of the federal season. Persons must comply 
with state laws further restricting the ship- 
ment or transportation of migratory birds. 
_ An amendment to paragraph 2 of Regulation 
No. 8, which is of great interest to breeders of 
game, permits migratory water fowl raised in 
domestication to be killed by shooting during 
the respective open seasons for waterfowl, and 
the sale thereof to state laws; but after March 
31, 1919, such waterfowl, killed by shooting, 
can not be sold or purchased unless each bird, 
before attaining the age of 4 weeks, shall have 
had removed from the web of one foot a portion 
thereof in the form of a “ V” large enough to 
make a permanent well-defined mark, which 
shall be sufficient to identify it as a bird raised 
in domestication. 
Another amendment provides that the plu- 
mage and skins of migratory game birds legally

killed may be possessed and transported with- 
out a federal permit. Provision is also made 
for the issuance of special permits authorizing 
taxidermists to possess, buy, sell and transport 
migratory birds. 
Two new regulations have been added. Reg- 
ulation No. 11 provides for the issuance of per- 
mits authorizing persons to sell migratory game 
birds lawfully killed and by them lawfully held 
in cold storage on July 31, 1918. Such birds 
may be sold under permit until March 31, 1919. 
Another new regulation is as follows: 
Nothing in these regulations shall be construed 
to permit the taking, possession, sale, purchase or 
transportation of migratory birds, their nests and 
eggs contrary to the laws and regulations of any 
state, territory or district made for the purpose of 
giving further protection to migratory birds, their 
nests and eggs when such laws and regulations are 
not inconsistent with the convention between the 
United States and Great Britain for the protection 
of migratory birds concluded August 16, 1916, or 
the migratory bird treaty act, and do not extend 
the open seasons for such birds beyond the dates 
prescribed by these regulations. 
This regulation is a restatement of the sub- 
stance of section 7 of the migratory bird-treaty 
act, and is intended to remove the confusion 
and uncertainty that exists in regard to the 
effect of the federal law and regulations on 
state game laws. 
The federal migratory bird-treaty act regula- 
tions prohibit throughout the United States the 
killing at any time of the following birds: 
Band-tailed pigeon; common ground doves and 
sealed doves; little brown, sandhill and whoop- 
ing cranes; wood duck, swans; curlews, willet, 
upland plover, and all shore birds (except the 
black-bellied and golden plovers, Wilson snipe 
or jacksnipe, woodcock and the greater and 
lesser yellowlegs); bobolinks, catbirds, chica- 
dees, cuckoos, flickers, flyeatchers, grossbeaks, 
humming birds, kinglets, martins, meadow 
larks, nighthawks or bull-bats, nuthatches, 
orioles, robins, shrikes, swallows, swifts, tana- 
gers, titmice, thrushes, vireos, warblers, wax- 
wings, whip-poor-wills, woodpeckers and wrens, 
and all other perching birds which feed entirely 
or chiefly on insects; and also auks, auklets, 
bitterns, fulmars, gannets, grebes, guillemots,
