of "Electrical Exhibition Addresses" by Prof. Robinson,
Mr. W. H. Preece, Mr. Slatter, and Mr. Andrew Sweet
(chairman of the Electricity Committee), with an introduc-
tion by Mr. Thos. Eccleston Gibb (published by Mitchener,
Camden Town). It constitutes an extremely interesting
summing up in a small space of public information upon the
subject of electric lighting from several points of view: that
of the consumer, municipal authority, engineer, and capitalist.
Mr. Eccleston Gibb speaks of the history of the electric
lighting legislation, especially with regard to the part St.
Pancras has uniquely played in the establishment of
London municipal stations. "The Corporation of London,"
he says, "which ought to have set an example, has
surrendered its powers to the City of London Electric
Lighting Company, and the honour is left to the Vestry of
St. Pancras to be the pioneer in London of municipal
enterprise in relation to electricity. Everything," he goes
on to add, "is now ready. Contracts for supplies equal to
nearly 6,000 lights have been sealed by the Vestry, and
this before a simple public lamp has been lighted." With
regard to the question of loan, Mr. Gibb alludes to the
difficulty with the County Council, and says, "If there is
any lack of
power, Parliament must be asked to
make such amendments as will put the Vestry and
local authorities in at least as good a position as
private companies." The addresses of which the book
consists are those of Prof. Henry Robinson, on "The Cost
of Stations," and Mr. Preece, on "The Poor Man's Light,"
which we have already given; also an address by
Mr. Slatter, giving elementary electrical information, and
prices for fitting up houses of different sizes. Mr. Andrew
Sweet deals with the question of the raising of capital and
the probable revenue. The book costs sixpence, and might
well be circulated in other districts than that of St.

Pancras.

the electric light into gas manufacturing operations." Well, I reply that our gas is frequently used in providing motive power to produce the electric light; and that being so, why should not we utilise the light for any purpose where it can advantageously be used? If Idare put gas lights where I have placed incandescent lamps, I could get as much light as I want, and at a cheaper rate than by using the electric light. Our surplus power, however, enables us to produce the light without much extra cost. We are intending to make some few additions to the fittings of the lamps, which will add somewhat to the cost, but which will at the same time be an additional safeguard.'”

Factory Lighting at Dundee.—Electric lighting is making great progress in Dundee, factory after factory having been lighted, and most of the largest factories are either lighted or preparing so to do. The most important installation yet introduced is that of Messrs. Grimond, Bowbridge Works. This installation, which has been erected by Messrs. Lowdon Bros., of Dundee, is amongst the largest in the kingdom. The factory alone covers four acres, and The installation there are 950 looms under one roof. is fitted up on the series parallel system, with a saving of 30 per cent. in copper. There are in the works three lamps of 300 c.p. each, two of 200 c.p., 85 of 100 c.p., 70 of 50 c.p., 54 of 32 c.p., and 1,960 of 16 c.p. each, which is equal to a total of 2,763 lamps of 16 c.p. each. For the ordinary lighting of the works there are two large dynamos of the Edison Hopkinson type, made by Messrs. Mather and Platt, Manchester. They are each constructed to give an electrical output of 300 amperes and 100 volts at a speed of 580 revolutions per minute, equal to the supply of 2,000 lamps of 16 c.p. each. The heavy mains are carried to distributing switchboards for each department, fitted with doublepole switches and fuses. The Edison-Swan lamps are fitted The Electric Light in a Gas Works.-The following with bayonet-jointed holders by flexible cord from a interesting note appears in the Journal of Gas Lighting, porcelain ceiling rose with safety fuse combined, and fitted which cannot usually be accused of giving commendation with enamelled shade over the lamp. In all, 35 miles of to electric light in any form. However, better late than cable and wire is used. The preparing-rooms are lit by It says: "The engineer and manager of the Dews- Sunbeam lamps of 100 c.p. to 300 c.p., in the spinning-rooms bury Corporation Gas Works (Mr. Charles A. Craven) two lamps of 16 c.p. are hung on the passes, and in the occupies now a rather unique position in the gas industry, winding-rooms 16-c.p. lamps are placed 10ft. apart. The inasmuch as he has adopted the electric light in a portion looms have also 16-c.p. lamps hung above them. A of his works. It appears that for some time considerable prettier sight is not to be seen in Dundee than when this difficulty was experienced in carrying on operations in the place is illuminated. Down the long passes and on each purifying-house, especially when extra work had to be side are lamps, the bright rays of which bring out in relief done in the winter season, owing to the inadequate light the looms, moving as if by some unknown force (the shafting furnished by the safety gaslights placed in the walls. Con- being all underground), and the hundreds of busy workers sidering how he could safely obtain more light for his men, who control the machinery. The calendering department, Mr. Craven decided that it could best be done by adopting which adjoins, is illuminated by lamps ranging from 16 c.p. electricity, and accordingly recommended the Corporation to 100 c.p. The recreation hall, which is another instance of to try incandescent electric lamps. To this they agreed, the Messrs. Grimond's solicitude for their workers' welfare, and the use of the light in the purifier and engine houses is brilliantly lit by eight 100-c.p. lamps suspended from the commenced on the 22nd ult., and, so far, this novel appli- roof in large diffusers, which make the light very soft and cation of electric lighting has been satisfactory. As the agreeable. On the "stage" there have also been placed 10 plan may commend itself to the notice of some of our 16-c.p. lamps, which serve as footlights when an entertainreaders, we give a few particulars of the installation, which ment is given. There is also a night or "police " circuit run Mr. Craven has recently forwarded to us. The lighting is through the works. It has two compound-wound dynamos at present done by four 16-c.p. lamps for the engine-house, made by the Electric Construction Corporation, Wolverand 10 similar lamps for the purifier-house, but it is hampton, and driven by a separate engine. Each dynamo in contemplation to replace two of the lamps in each house is capable of lighting 200 lamps of 16 c.p. each, and either by others of higher power. The dynamo was specially machine can be driven separately or both at once, as made by Messrs. Austin and Myers, of Armley, Leeds; and required. One dynamo is kept running all night. Hand up to now it has run well. It is located in the engine- lamps of 40 c.p., with flexible conductors, are also used when house, and is driven direct from the flywheel of the repairs are carried on. In the street outside four 100-c.p. stationary engine. To the foregoing details, Mr. Craven and 10 16-c.p. lamps are fitted. On any alarm of fire the adds the following general remarks: 'Some of my brethren hose is run out, the door opened, and the whole night in the gas profession seem much struck with the novelty circuit is thrown on automatically. The installation is a of the idea. I am told that it is "a funny thing to bring great credit to both owners and contractors.
