! HOW THE OFFENSIVE GASES FROM THE ''Li
TRAINS CAN BE DONE AWAY wITH-THE USE
OF COMPRESSED AIR MOTORS SUGGESTED.
] MIR. +. Henriques. the president of the Pneumatic
Tramway Engine Company, has addressed letter to
William r. Garrison. president of the Manhattan
Company, in which he says his company will con-
struct one of their compressed air motors of sufli-
Gent power to propel one of the four-car
trains of the 81" roads, provided permits
sion be given for its experimental use on
the latter roads. HERALD reporter called upon
Mr.. Garrison yesterday to ascertain what action
would be taken on the subject by the Manhattan
Company in view of the loud complaints which are
being made daily by not only passengers the
trains but also the part of persons living along
the line of the roads, against the fumes OF burning
sulphur and the carbonc acid gas emitted by the To-
comotives. Mr.. Garrison said the communication
had only reached his hands a short time before and
there had been no opportunity to consider the prop
ositon. but that it would receive due attention in
day or two.
Mr.. Henry Harley. the general agent OF the Tram
way Company. was engaged in explaining the work
ing of the compressed motor to party composed
of Mr.. D. Shafto Hawks, of London; John q. Moore
tho former representative of the Erie Railway at
San francisco, ana Mr.. Charles Rachette Of this
Tramway Companys depot, at the upper end
of Second avenue yesterday afternoon. The motor
which it is proposed to place on the al" roads is
the which has been in successful operation on
the upper division Of the Second avenue railroad for
several months past. In explaining it's merits
