Two only are being used at the present time. Provisionis made in the construction for additional units in case the voltage or otheroperating characteristics of the line are altered. Pressure treated southern pinepoles were used for this line. A number of line anchors and dead-ending structureshave been introduced into this line. About one-half of the structures are erectedand materials for stringing conductors have been assembled. 1920 HYDRO-ELECTRIC POWER COMMISSION 79. 80 TWELFTH ANNUAL REPORT OF THE No. 49
