receive hatch auI distribute the eggs OF fishes furnished
by The United states Fish Commission. About 4,OOo00O
eggs Of California s1u0n thus distributed IN Oc

DFsIRABuITY OF BEssElfER RAus.-A recent
report Of the Cologne-Nndeu Railway Germany, fur
nshes abundant statistics showing the excellence Of Bes
scmer rails. The most striking Of the observations was
made upon portion q the road where more than twelve
years ago Bessemer steel rails crueibc steel rails ana
iron rails laid side by side. There were two classes
Of iron rails Of of these than so percent nave

the crucble steel rails had be read The Bessemcr

MIGRATioS OF INsECTS.-PTOfessOr Riley re-
cards the migration OF insects as due 10 their multiply
ing more rapidly than their means Of support. The
nigraons OF rats are attributed 10 The cause and
similar observations have been made 70 other an
finals. Many insects that not normally OF migrl
tory tondrncy exhibit when pressed by dearth OF food
In these eases they collect together and migrate in large
bodies Referring instances OF the Kind, Professor
Riley at recent meeting of the st. Louis Academy OF
Science stated that vast flights Of butterflies took place
al times from the equatorial regions OF south America.
Migrating swarms have been observed at and also
In the southwestern parts OF the United States where

SOUNDINGs IN SWIFT CURRENTS.-A cor
respondent asks information to how sound
ings are obtained where the current is rapid for in
stance between :hc Mississippi etties where it IS
ported at six miles per hour soundnes in rapid cur
rents ar taken with very heavy lead After the boat
IS anchored the the the line
ried rapidly alongside aud the lead taken up the stern,
This requires some cxperuess; but fortunately. cur
rents six miles per hour do not in very deep
water That this method lnay be made viii be
seen from the fact that sounding lead will descend ten
fathoms in three seconds towing line after it in the
same space Of time q siX-nilc current will have run
twentyfour feet Sometimes the lead s. carried up
the requisite distance IA another boat. The
depth usually known approximately 50 That the loose
line and the station Of the leadsnan can be arranged be-
forehand.
