FOR 1s72.-The annual report Of the Depaftnentd

ending June 90 1872, has made It's appearance, and
ike its predecessors contains a large amount q
valuable statistical information IN regard 70 the
several branches inclnded under the above neh-

WASHING Wool AND UTILIZING THT ErrSE.-
The custom Of sheaging sheep without pre'io|
Washing and sending tho wool directly 10 r7iall,sh-
meats that wash it on large scale has laiey
become so prevalent that consideration oi
tho methods employed and the refuse obtained f.
worthy of attention The usual scourIu g-na'hlue
were necessarily unsuited for the treatment of suoG
wool as giving results unsatisfactory ~ quality and
quantity and the so-called Leyiathan or 4. machine
similar in character was adopted. This consists n
the main of two steepiug-tubs and two securing
tubs, each tub having a pair of iron pressing
rollers the upper one in each case being wrapped
with bempen cord and covered with cloth The wool
being brought to and taken from the rolcrs on IN
endless cloth. The stirring apparatus OF t1e scour
ing-yats also delivers the wool 30 c Satlug forks
which place it upon the feediugcloth. The secured
wool is rnsed in a tub having similar stirring
apparatus and an abundant water supply. All the
tubs have stop-coclls in the bottom and perforated
false bottoms to retain the wool when thcJ arc emp
tied. Tue first three tubs can be warmed by steam
pipes The wool is placed in a steeping-tub ~
warm water whereby the adherng eXcrcment and
dirt are for tho most part removed; ond since two
such tubs are employed in turn. thee - ample time
for dissolyng the dirt any undissolyed particles
being rendered more readily soluble by passing
