The electric clock and fire-alarm maintenance, which has in former years been done by contract, is now done by employees of this division. The expense, as compared with the contract method, is as follows:

Total cost by contract (1908) . . . . to o so $6,900 38 Total cost by this division (1909) . * g g * g 4,869 54

A charge of $655.50 for new tools and equipment, and a charge of $150 for maintenance brought over from last year, are included in the cost of work done by this division. The actual cost of maintenance should therefore be $4,064.04, making a net saving of $2,836.34. The number of clocks maintained during the year 1909 was also 17 per cent greater than the previous year, and an increase of 46.5 per cent was made in the number of buildings equipped with fire-alarm apparatus.

A detailed schedule of equipment is now being compiled and will be issued as a separate report.
