l. REMOVAL OF SMELL FROM Hog YARDs.-Prof.
FTorsford has lately been making experiments in ref
/
of the nuisance caused by the establishment of eX-
| tensve hog yards IN the vicinity of cities, with
especial reference to those at present near Boston,
Ii may create a smile of increduty on the part OF
our readers to be informed that at the present time
Boston, as pork packing center, is second only to
| Chicago. having long since distanced Cincinnati
| and other Western towns in the race, and that,
probably, within comparatively short time, 1t VIII
outrank even Chicago This Is due to the facilities
secured by the Boston merchants for the transfer of
live stock to the last rather than the packed pork,
and to the very complete and efficient labor-sayine
| arrangements for doing the work on large scale
| and at very tritling cost
! Here however as elsewhere the Odor developed
by the concentration of many living hogs has be-
come very disagreedble TO the ncghborhood; ana
Prof Hor5ford. expert has been called upon 20
devise remedy. He reports that he has succeeded
| in preparing liquid which, when sprnked TO the
amount of about pint to each animal upon the hogs
and their surroundings, will entirely remove the pc
culiar odor SO as make it napprcciable. ms is
also to be applied TO the floors and sides OF the cars
| in which the animals are transported When once
within the pens and supply of charcoal spread
upon the floor the carnations are almost completely
| overcome.
Ii is now proposed to thatch with straw the board
walls of the space where the hogs are last handled
before dropping into the scadIng-tank. lhlS Will
reduce the noise to a minimum and Tenderlt almost
inaudible beyond the walls of the mclOsure Prof
H0TsfoId thinks that the problem of the possibility

is satisfactorily solved.
