Of the 594 inspections made during the year ending Dec. 31, 1914, including those of gas supplied by municipal plants, 251 were made by the chief inspector. The following tables contain the data obtained by these examinations. For convenience of comparison the oil-gas and acetylene-gas companies are shown in separate tables.

It is to be noted that the candle power at the Chelsea station was taken with a Sugg's Argand burner, D size, old style, and a six-inch chimney, and at the East Boston station with a Sugg's F size, new style, and six-inch chimney; at the Chelsea station this latter burner gave 15.9 candle power. Number 200 was a sample taken at consumer's house at the end of a high-pressure main in investigating complaint of poor service. Number 203 was taken at a routine inspection showing low candle power. Numbers 199, 201 and 204 were taken at routine inspections after changes had been made in method of manufacture of the gas supplied. The other samples were analyzed for information. A study of the inspections of the companies made during the five years from 1910 to 1914, inclusive, shows the following facts: From Nov. 30, 1913, to Nov. 30, 1914, inclusive, there were 80,428 meters inspected, including 21,276 prepayment meters, as compared with 88,279 during the preceding twelve months. Of these 21,276 prepayment meters there were 6,731 three lights, 14,484 five lights, 53 ten lights, 6 twenty lights, 1 thirty light and 1 fifty light. Meters which pass inspection are sealed on the top with a brass badge having the inspection number and a wax seal bearing the date; in addition, the fronts and backs are sealed, thus preventing the opening of the meters. Whenever meters are opened for any purpose they must be again tested and sealed before being placed in use by the company. Of the meters examined in the year ending Nov. 30, 1914, 287 were known as complaint meters, the others being new or recently repaired. The following table exhibits a comparison of the number inspected annually during five years: |
