From the Washinq,on Star
The Subsistence Depot ut Washington.
rev are aware of the immense amount of prOvi-
sions daily arriving in Washington, or of the extern
sive arrangements made for the protection and
storage OF supplies. Hundreds have focked to the
railway depot to witness the arrivals of freight,
unconscious of the existence of another depot into
Whlch more Is pouring daily than arrives BY rail in
week The receiving depot for supplies is located
at the Western Wharves, where about twenty very
large storehouses have been erected and filled,
whue score of workmen are erecting others as
dpiuy as possible, yet unable to meet the pressing
en- manu- ior storage room. These buildings are
@ na,V" up az the rate of one and two day, while
vdst amount of barreled hcef pork &c in long
IeFs, are protected by boards laid over the top
Notwithstanding the facilities for unIoadinp the
vessels here, there are nearly half dozap conS
stantIy awaiting their turn, and tups are nufing
around, pulling the vessels about in a remarkabIv
irlsky manner. This place is the receiving depot
Tor the ratiOns of the troops here, together with
oats hay, and other appurtenances of military op-
erations.
There are here over 5000. 900 ratons, of which
there are $4,000 barrels Of flour, 1900 barrels of
beef, 5000 barrels of pork, 500 600 pounds of cof-
lee, 5OO goo pounds of sugar. and 1900 900 pounds
OF bread, with homing, crackers, vinegar, candles,
soap, etc, IN proportion. Immense cargOes of hay
ana oats are daily arriving, and the yard is
thronged with teams loading for the respective
camps Seven large iron boilers are kept busy
oolhng meat for the troops arriving at the depot
ana other places prior to their permanent location
IN camp. Several large schooners discharging
ice just below the storehouses for the hospitals and
camps, and three or tour coal vessels add to the
forrest OF masts and rigging at the Hharves. Not

than at the railway depot, and visitor is struck
wiIh the order and system with which everything
Is done There is little of the shouting and con(u-
sl0n usually among teamsters; and contrary IN the
custom elsewhere, when bale of bsy or sack of
oats Is set down 1t remains there until removed by
the proper authorities.
Need of Artillery.
Fritz Anneke, writing from IIirslanden. near
Zurich, Switzerland to the New York Tribune.
says:
A sufficient field artillery means about tbreo
pieces per 1000 men of infantry or cavalry. rather
more than less for young and ipe.neriapcad
troops such as our volunteers are. To be etfsc-
tive, 1T shou id not only be able to shoot well hutt
move upon the batte-fi- Id almost as easily and az
quickly as cavalry, and besides, should be regard
ed as an arm by itself, not as mere appandiv IN
otheT arms-to infantry, rifemcn or cavalry;
should be commanded by its own officers subjected
only to the orders of the chief cCmrander: bv
men VINO understand thoroughly its use, who know
not only how to move batteries, but divisions of
~ w. 9o' ana more pieces IN one solid mass, who
know where best to place them, and how to direct
Their fire. few pieces drawn by men, as at the
Big Bethel affair, or few stray cannon attached to
a regiment of infantry not entitled to the name
ot held artillery. Except under peculiar circum-
stances, field artillery should never be used in
Smaller bodies than batteries of six or eight pieces
to be attached to brigades or divisions of the other
arms For this purpose, however, not more than
or at most 0ne-half of the total strength
OF the Held artillery should be employed while the
balance ought to be kept in reserve united, under
one commander for every corps P arDee, and to
be used en- mosse, for batteripg down strong posi-
tIons OF the enemy, for preparing victory, or in
cases OF mishap Tor covering retreat.
