VISITORS TO THE LIBRARY

Visitors to or users of the Library during the year were counted at the entrances as follows:

CHANGES IN PERSONNEL

The few changes in the personnel of employes which occurred during the year were entirely in the subordinate positions, and are classified as follows:

Of those who resigned almost all stated that they could better their condition elsewhere.

CEILING LIGHTS

The ornamental leaded glass ceiling lights throughout the building were found to have gradually sagged from weight and required immediate repairs. These have all been raised to the original position, additional supports installed, and broken glass replaced. Electric outlets have been installed above the ceiling lights, so that hereafter the glass can be kept clear of dust by use of small vacuum cleaners.

DRINKING WATER

The difficulty of obtaining perfectly clear, clean ice and handling it to insure absolute safety caused this office to begin the elimination of the tank water coolers and adopt the bottle type of cooler. This has considerably increased the expense of distribution, and it is to be hoped that provision can soon be made for a circulating system for drinking water.
