property there would be only one side open to the country.
But it appeared, from the cross-examination of Mr. Gurney,
that the estate was in Chancery; the house, which for many
years had been uninhabited, was in a very dilapidated state,
and the communication with the town very bad. The two
lines of railway also passed so as to be equally disadvan-
tageous to the property.
Mr. Chennel, official cern-seller at Guildford, stated that
the quantity of corn brought to that market varied from 400
to 700 quarters a week. The supply came chiefly from the
south, and but little from Petersfield, and his impression was
that the intercourse between different parts of the country
would be greatly increased, though of course that would to
some extent depend on the number of stations.
Mr. George Sayers, a waggon-master at Guildford, stated
that the carriage through Guildford to London was chiefly
for live stock, and the return was for groceries and other
similar necessaries. This witness testified to the traffic from
the several places in the neighbourhood, and he stated that
by far the larger part of it came from Chichester, and but
very little from Petersfield, the business at the latter place
being trifling.
The Committee adjourned till to-morrow, at twelve o'cicck

(Continued from our Afternoon Edition.)
Mr. Brunel was then called, and the purport of his evidence
was that the proposed line would not injure the house or
demesne of Lady Fane ; that it was not nearer than three-
eighths of a mile, and could not even be seen from the house
of her Ladyship.
Mr. Giles, C. E., and Mr. Batten, were called on the part
of the petitioner. The former stated that a better and a
cheaper line might, in his opinion, be constructed along the
river Yoe.

The Committee having consulted for a short time, they de•
cided that the preamble was proved.
The Committee then went on to consider the clauses.

NORTHUMBERLAND (ATMOSPHERIC) LINE.
This Committee proceeded this morning to hear the evi-
dence in favour of the promoters of the Newcastle and Ler-
wick line, and against the Northumberland (Atmospheric) line.
Mr. Bidder's evidence occupied the attention of the Com-
mittee the entire day. Ile stated that he had made
several experiments from the formula of Mr. Hawkesley, a
large gas manufacturer, and he found that on the atmos
pheric system they could not procure a vacuum of fifteen
inches in less than nine minutes, with two engines of fifty
horse power each, and with twenty-two strokes per minute.
The greatest speed which could be attained would be 33
miles an hour. The resistance would be 14 pounds per ton,
and the train would meet the same resistance in return.
Forty-five tons could be carried at the rate of thirty miles
an hour on a level, with a vacuum of fifteen inches; and
thirty tons would be conveyed at the same rate on a gradient
of 1 in 100.

Mr. Bidder was then cross-examined by Mr. ALEXANDER
—He did not think that the valve in the piston would have
any great effect in stopping the train by admitting atmos-
pheric air. It would not admit it quick enough. He
thought that it would, in certain cases, have the effect
of retarding the train ; but in most cases it would
not be brought into play at all. He never saw a piston
fitted with valves for retarding. The revolving power
was objected to; it wore the engine. They were
obliged to use it passing stations, but they always
avoided it when it was possible. He adopted Mr.
Hawkesley's formula, and it was on that he founded all
his experiments, the application of Dlr. Stephenson's for-
mula created what appeared to him to be anomalies,
because Mr. Stephenson did not allow sufficient
for the friction of the air. When he analysed Mr. Samuda's
formula he found the same. He • believed Mr. Hawkesley'e
formula to be correct, and to account for the anomalies of the
formulas of Mr. Stephenson and Mr. Samuda. By Mr.
Stephenson's experiments a vacuum of eighteen inches was
obtained in three minutes all but two seconds. The leak-
age depends on the length of the pipe. The experi-
ments made with respect to the atmospheric resist-
ance were quoted in Robins's Mechanical hPilosophy,
and were made many years ago by order of Government.
The result of these experiments, hi: believed, was Mr. Brunel's
apprehension that he would not be able to attain a high
velocity on the atmospheric principle.
The Committee then adjourned till Wednesday.
