Here,
however, the buckets were placed on wagons standing at the curb, as
shown by Fig. 3, Plate LVIII.
Blowers for ventilation were installed at each shaft, as at First
Avenue, and, after the excavation had proceeded some distance, small
blacksmith shops, for sharpening drill steel and making minor repairs,
were located in the tunnels near the shafts.
The concrete plant in each shaft was similar in arrangement to those at
First Avenue, but the storage bins had wooden walls made of 2 by 4-in.
and 2 by 6-in. scantling nailed flat on each other.
The contractor's office on 33d Street backed up against the 32d Street
shaft site, and the basement was used as a storeroom for supplies for
both shafts.
After the decision to do part of the work between Sixth and Seventh
Avenues in open cut, an 8-in. air main was laid in 33d Street to the
West Shafts, and air was supplied from the Intermediate Shaft for work
on both streets in that neighborhood.
_West-Shaft Plant._--West of Sixth Avenue, between 32d and 33d Streets
and adjacent to the open-cut sections, the Railroad Company obtained
from the Hudson and Manhattan Railroad Company the use of a large area
from which the buildings had recently been removed, and gave the use of
it to the contractor. This was of great value in prosecuting the west
end of the work.
