fitting tin spice box is nice for holding cheese. A tiny "salve" box should contain salt and pepper mixed. Sew leather straps on the cover of the basket inside, for holding knife, fork and spoon.

Put a strap around the basket that you may hang from it a little pail containing cold soups recommended for drinks in summer. Cold puddings should be wrapped in strong writing paper, then in wrapping paper and pinned close.

The Final Report of Professor S. H. Woodbridge on Steam Heating and Ventilation of the State House.

MY DEAR SIR: The work given to my care by the Board of State House Commissioners has been executed in as close accordance with the plans proposed in my communication to the Board under date of June 8, 1889, as has been found practicable.

The apparatus advised consisted of a fan and engine capable of moving and distributing under slight pressure 25,000 cubic feet of air per minute, a heater capable of heating that air from 20° below to 70° above zero, a system of iron conduits and of wall flues for the distribution of this air throughout the extension and to both the assembly halls of the main building, a system of dampers for the control of the quantities and the direction of flow of the air moved, a system of direct steam heaters under automatic control for the even warming of the rooms; boilers and chimney of sufficient capacity for the required work, and a system of vent flues and channels for the discharge of vitiated air.

The several parts of this combined system were in plan carefully proportioned to their required individual and associated duty and to the ordinary and the special requirements for which they were designed. Departures from that plan have been chiefly due either to modification in the building itself, and in required adaption to such changes, or else to the limited means at the disposal of the commissioners for the execution of the work.

Trials of the system have been personally made under conditions of weather favorable to a test of its ability to meet assumed maximum requirements. The results of the tests are herewith submitted in some detail, together with such notes as appear of possible value to a clearer knowledge of the purposes for which the several parts are designed and the method of their use for obtaining the best results.

THE FAN.-With the conduit dampers arranged for the movement of a maximum volume of air, the amount passed through the fan when making 196 revolutions a minute was found to be 21,000 cubic feet at 4° (F) or nearly 25,000 cubic feet at 70°. A higher fan speed and a proportionately larger volume of air moved are easily obtainable by the use of a higher boiler pressure than the thirty-six pounds carried at the time of the experiment. The specifications called for a maximum of 25,000 cubic feet per minute, with a fan speed of 250 revolutious.

THE HEATER. The heater is made up in three sections of about 340 square feet of steam-pipe surface each Two of these sections are connected with the boilers and one with the engine for the use of exhaust steam and the utilization of its heat. It is specified that this heater shall be capable of warming 25,000 cubic feet of air per minute from 20° below zero to 70° above. With steam shut off one of the boiler sections, and but five pounds steam pressure on the other, the exhaust steam from the engine filling the third, the temperature of 21,000 cubic feet of air a minute was raised from 4° to 65°. By increasing the steam pressure in the one coil used for boiler steam to forty pounds, the temperature of the air could have been raised to 85°. There can, therefore, be no question as to ability of the heater to perform the stipulated duty.

The absence of the by-pass called for in the specifications is a matter of oversight on the part of the contractors, and it is hoped that the commissioners will not accept the work as complete until that needed means of regulating the temperature of the air flow is provided.

Its purpose is to allow a part of the cold air to pass by rather than through the coil, and to mix it with the heated part of the air before its passage through the fan in such proportions as to furnish the wished for temperature in the mixture. In case such by-pass is not supplied the sectional form of the heater furnishes a means for an approximate regulation of temperature. General directions for their use for such purpose are as follows:

AIR DISTRIBUTION. The iron conduits are proportioned for a maximum flow rate of 1200 linear feet per minute, and the area of the flues are scheduled for a flow rate of 600 feet. By means of dampers in the conduits and at the bases of the flues the air movement may be directed and distributed as desired.

It is assumed that the rooms are to be continuously warmed and ventilated only when occupied, and that the air furnished by the fan is primarily for the purposes of ventilation and not for heating. For ventilation alone the air need be heated only to the point of comfort, as 70°, or under. If, as in early morning heating, the fan current is also used for warming, its temperature may be anything desired within the range of the apparatus.

The method of quick heating in the morning by a rotation of the air of the rooms through the fan is to be recommended on the ground of economy. In all but the severest weather the steam may be shut off from the extension at night, and at six o'clock or later next morning the doors may be opened between the rooms and the hallways, and from the basement hallway into the fan room, and from the fan room into the heater's connection with the window. Steam may then be put on the entire system and the fan started. One hour of rapid circulation will generally be found sufficient to bring the rooms to a comfortable temperature. At eight o'clock the fan and heater may be adjusted for their day's work of ventilation only.

The air is to be directed where the occupants are assembled. When the Senate and House are in session, the air is to be cut off from the committee rooms and directed to the assembly halls, and vice versa. The only rooms which it is necessary to continuously ventilate are those permanently occupied by the several departments of State.

The schedule of rooms supplied directly from the fan is as follows: Rooms marked (C) were at the time of scheduling assigned to committee uses, and all others to State departments. All work has been done on the basis furnished by this schedule, and the system cannot be held responsible for any results growing out of changes from the schedule arrangement and uses of rooms.

The supply for department rooms is based on the largest number of permanent occupants each is likely to accommodate, and that for committee rooms on a maximum rate of air change of six times an hour. The tests were confined chiefly to rooms farthest removed from the fan, as those most likely to be given less than their proportion of supply. All tests made in the basement and first floor
