Again, since the solution is rath~r expensive, in order
that there be neither overlapping, nor omission during spraying,
some means'must be devised to identify what area has been
covered. 'Some thought has been given to equipping the vehicle
with a separate nozzle for pouring a colored liquid dye to
outline the outside edge of each spray pass.
Suggested
Equipment Units for Applying Solution
For:median strips up to 40 feet, roansides, outside edges of
interchanges, and narrow dividing islands:
One (1)1,000 gallon tank truck with extender arm type bOom,
hydraulically operated, a minimum of 20 feet in length.
For'wide median strips and dividing islands (over 40 feet),
loces and bowl areas of interchanges and other "hard to reach
areas":
(a) Two (2) jeeps or equivalent vehicles (4-Wheel Drive)
with dual tires on rear.
(b) One (1) 250 gallon
tank.
, (c) Fixed hori zontal boom..
. ,'(d) Mast type borm,
(e) Hand operated boom with hose attachment for
manual spraying of slopes, around trees and
shrubbery, and other inaccessible areas.
, In. addition, a 2,000 gallon tank truck to be used to supply
water' tb mix new batches of solution in the tanks of the abovementioned
spraying vehicles.

, Massachusetts' research in this field began with MH-40 in
1953 with twelve (12) half-acre plots on Route #1 in Danvers,
with encouragin~ results.
[he: following year se~ected areas on a much larger mileage
scale were treated on a state-wide basis. While results in
certain instances were desirable, other areas, because of poor
applica~16n, were none too conclusive.
