The Dust Nuisance. 
The dust nuisance and the insufficiency of the highways 
in the British Islands for rapid or very heavy traffic being the 
difficulties which road reformers are seeking to overcome, it is 
advisable to consider briefly what has been done or proposed to 
secure the needed improvements. The motor car has come to 
stay. In its heavy form it concentrates heavier loads on the 
foundations of roads than ordinary vehicles impose, and in its 
lighter and more rapid forms it causes the dust nuisance. 
To remedy the dust nuisance it is necessary to take special 
pains by careful construction and maintenance that the roads 
shall be as dustless as possible. This, with ordinary macadam, 
can, in many places, be effected by the cross sweeping, which is 
a necessary part of good road maintenance. On very important 
lines there would be little difficulty in applying, for the removal 
of dust, a pneumatic machine similar to that now used to extract 
dust from carpets and house furniture. The makers of motor 
cars should continue to direct their careful attention to an 
investigation of the best form of cars, wheels, and tyres, for 
lessening or preventing the fanning and suction action which 
raises the dust. The action of a car in this respect depends not 
only on the form of the carriage, but also on the way the 
springs are fixed and the steadiness in running of the engine. 
The absolute cure for the dust nuisance would be the use 
of (a) macadam fixed by tar or a similar binding material of 
better quality ; (V) kleinpflaster, otherwise known as hand-set 
or armoured macadam ; or (c) brick or stone pavement. Roads 
constructed with these materials are easily cleaned, and motor 
cars can be propelled on them with the minimum tractive 
force, and, as a matter of course, travel more smoothly on 
them than on the best ordinary macadam surfaces. It appears 
to be idle to try to find a cheap liquid material which will fix 
or keep down dust on an unscientifically constructed road 
surface ; the cost of such materials would be better expended 
in making a permanent improvement in the road crust. 
Those in charge of our highways may be fairly expected 
to give special care, in the interest of motorists and the 
public generally, to the proper banking up of the road on the 
outer side of curves and to keeping hedges and trees well cut 
down at the same points, and near cross roads, to enable the 
road to be seen as fully as is possible for some distance ahead. 
Roads may be so banked up at curves without any disadvantage 
to ordinary traffic and without adding to the trouble or cost 
of maintenance. In any case, all deep channels and low sides
