“(1) A means of healthy recreation and health restoration to dwellers in 
crowded cities. 
“(2) A revival of road touring on a great scale, and consequent revival 
of the country inn, good custom to which brings prosperity in its locality. 
“(3) Convenient transit for passengers by which they can be taken up and 
set down at any point or house. 
“(4) Omnibus traffic in towns with reasonable acceleration, and a cessation 
of wearing-out cruelty to horses. 
“(5) Feeding the railways at points on the main lines without the use of 
branch lines. 
“(6) A great increase in the range of delivery of goods from door to door,

“(7) Mechanical traction for work on the land, ploughing, harrowing, reap- 
ing and carting both to markets and on the farm being done by one power

“ (8) Assisting to prevent the congestion of large towns. 
“ (9) Greatly improved sanitation by the elimination of foul matters from

The other side of the question is ably set out in an article 
in the Quarterly Review , published in October, 1906, and was 
lately stated briefly by Mr. Hawkshaw, Past President of the 
Institution of Civil Engineers, who said he quite appreciated 
the advent of motors, and their great convenience and useful- 
ness, but it was no good overlooking the fact that motor traffic 
in its present stage had already done much to destroy the 
pleasures and comfort of country life. 
The Construction of Good Roads. 
The difference between a successful roadmaker and one 
who fails in his efforts is of the same kind as that apparently 
subtie, but, in truth, simple difference which exists between a 
good cook and a bad cook, a successful photographer and one 
who fails to obtain good pictures. The success or failure may 
be based upon the use of exactly the same materials and exactly 
the same appliances, but we all know the wonderful difference 
in the results. The success is due to precise and thorough 
attention to details, some of which appear to be unimportant, 
and the failure to the absence of such attention. 
Neither Telford nor Macadam originated the use of stones 
broken to a small and uniform size for the upper crust of roads, 
but they were the first men in the British Islands who, in 
professional labours, carried out effectively scientific views in 
road construction and maintenance. They were good cooks ; 
those who preceded them and many who followed them were 
bad cooks. 
Some of Macadam’s views, especially as to the foundations 
for roads, were quite erroneous and were vigorously challenged 
by his contemporaries. At his instance, macadam was sub- 
stituted for stone paving in some parts of London and, as 
might have been expected, proved quite unsuitable. As to
