with which lies the difference between practical success and failure.
Thus it is not merely sufficient to heat an oven for bread baking; it is
also necessary to heat it within the times and according to the habits
of work to which the baker has been accustomed. Work in town bakeries
begins at about midnight, or shortly after, and the condition of the
oven must conform to the requirements of the dough, which vary from day
to day and from season to season. In order to master all these niceties,
as far as a knowledge of them is necessary to his purpose, Mr. Booer
has spent many nights in the bakehouse in the Blackfriars Road; and has
thereby obtained a command over the technicalities of the work which has
served him in good stead, not merely for adjusting his gas heat, but in
answering the innumerable objections always raised when a revolution in
an immemorial trade is threatened. It is with considerable satisfaction
that we are enabled to declare, after duly weighing all the conditions
as to first cost and otherwise imposed by himself and others, that Mr.
Booer has succeeded, upon these terms, in vindicating the claims of gas
to be a cheap, efficient, and cleanly fuel for heating ovens under the
control and according to the methods of working of the baker himself.

The oven with which this success has been achieved is one of two in the
bakehouse of Mr. Loeber, of 161 Blackfriars Road. It measures 7 feet by
6 feet internally; being what is technically termed a 6 bushel oven. The
alterations made by Mr. Booer consist in the first place in the removal
of the flooring tiles, and the laying down of a new bottom, under which
run a number of flues radiating from the side furnace. The throat of the
furnace, where it enters the angle of the oven, is bricked up, and eight
pieces of 3/4-inch gun-barrel tubing project above this dwarf wall,
and radiate fan-shaped under the dome of the roof. These are the
gas-burners, which are supplied from a 11/2-inch pipe led into the old
furnace. The same pipe supplies the similar burners which are inserted
