The first two items would, perhaps. suffice for
wooden trestle from New Jersey avenue to Az
street, and reserving the more expensive con-
structon of the viaduct until it shall be con-
sldered necessary to put the roads under ground
west of AZ street. The beam tunnels might for
the present be omitted and temporary wooden
bridges be substituted for them.
The grand total represents a considerable ex-
pendlture; but the cost may be urged as an OBJ
lection to any plan for changing the present
location OF the tracks, and would be urged with
much greater force against any other line than
the one selected, If it served the purposes in
tended in this one. No temporary scheme
should be considered at all. 1t is better to let
the tracks remain as they are than shift the
nuisance to other localities only to be shifted
again. That the present plan is an economical
one appears in this that it serves the purposes
intended at minimum of cost
The 4th avenue improvement in New York
city, designed to accomplish precisely the same
results, has recently been completed. The
length of the line differs but little from that of
the one here proposed, yet the cost was about
under thoroughly competent and careful man
agement. The lesser cost of the proposed
route through Washington is due
to the natural advantages of the line selected.

Inc Building of the causeway, having side slopes
OF earth, will constitute part OF the reclama-
ton OF the flats over which it will extend, and
will be made from the surplus excavation for the
tunnel. The small amount of masonry required
for joining the side roads over the tracks at the
commencement of the viaduct will rest on piles
| to be driven before the filling begins.
am indebted to Mr.. Allen Campbell, formerly
commissioner of public works and now comp
troller of New York city. for the detailed plans
OF the Fourth Avenue improvement, recently
completed in New York. These have been care
fully studied in connection with the proposed
improvement here
