date, but apparently Of the same per | iod. We were informed no attempt has been made since that date to rec ord on these maps additional pipes additional mains or lines. changes in sizes of mains or lines. or mains or lines which are removed. For in- stance, there is no record as to the number of gas services or the mum Der of electric services. There is no record of the number of customers installations of gas ranges, water heaters or the like. nor could VIC find anyone who has any idea as to the number actually installed. Without accurate record Of the gas mains or Iiously difficult if not impossible for one to state whether the same are adequate for either the present needs or future requirements.
 One of the first things nccesssry would be for the department to se- cure the services of q. bright young man to make a survey of the entire property, both gas and electric, and prepare q map and records Of both gas and electric showing the property owned by the department and the amount and character of the appara- tus installed and owned by the GUS records be kept of future changes which are made from time 10 time.
 4 f1reproof vault should be obtained for the departments office records.
 
 is otherwise not fireproof and the de- struction of the departments books and card records would cause con- siderable loss and inconvenience. Tar.
 The department sells tar at dif- ferent prices. according to the quau- tity purchased. For single barrel lots the department receives $4 per bar rel. Larger quantities are sold at 1 cents per gallon and when sold in bulk in large quantities the depart ment receives cents per gallon. The records of the company show that for the twelve months ending April 30, 1916, the department sold 32 per cent. of the amount of tar which Is record - cd as having been received. and for the ten months ending February 26. 1917, the department sold but 34 1-2 per cent. of the tar recorded as hay ing been received. The records show that the tar shortage tanks at tho gas ing the greater portion of the two year period. The remainder of the tar has been allowed to go to waste by draining out into the Shetucket river and we understand the same state of affoirs eristed prior to the period mentioned.
 Tar pollutes the Shetucket river' and necessitates taking apart for cleaning the condensers of the steam turbines in the electric power station each week during the summer.
 Tar has a considerable value of fuel, especially during the present high cost of coal. Tar at 1 cent per gall lon has a fuel. value equivalent TO coal at g per long ton, consequently 3c tar equals $6 coal. This $6 per ton for coal would have to include cost of unloa adinS from the cars, piac- ing it in front Of the boilers and re- moving the ashes. The Sc per gallon for tar is net excepting for the amount of steam required to heat tho tar.
 Tar is regularly burned under the boilers by the Brooklyn Union Gas company, the Consolidated Gas conn pany etc.
 The present amount of coal tar at Norwich Is about 5000 to $500 gallons per month, equiVa lent to 27.5 tons of coal. the water gas tar will be in ad- dition.
 The present tar storage capacity at the Norwich Gas plant is appro&- rnately 120, GOO gallons. equivalent to $50 tons of coal. We recommend that tar burning apparatus he installedand the tar on hand utilized-then fire the boilers with coal and coke until the tad reservoirs are again nearly filled when the tar will again be burned.
