120 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



The line has been brought to its present satisfactory condition 

 through the fine cooperation of the Coast Guard, which is largely 

 interested in the upkeep of the pole line, as a metallic telephone 

 circuit is maintained thereon, connecting near the Hatteras station 

 with the Coast Guard line to Morehead City, K C. 



WHITEFISH POINT-VERMELION POINT (MICH.) SECTION (TELEPHONE). 



For a number of years past replacement of poles and wire have 

 been made by the Coast Guard and at its expense as the old mate- 

 rials became unserviceable. As practically none of the original line 

 remained, jurisdiction and control of the present line was turned 

 over to the Coast Guard on March 1, 1923. 



BEAVER ISLAND-CHARLEVOIX (MICH.) SECTION (TELEPHONE) ; NORTH AND SOUTH 

 MANITOU-SLEEPING BEAR POINT (MICH.) SECTION (TELEPHONE). 



These lines, consisting of both cable and land lines, although con- 

 structed 18 and 20 years ago, respectively, worked satisfactoril}'- 

 throughout the year. The Manitou lines are operated by Coasn 

 Guard officials, who perform the necessary occasional work of repair 

 and upkeep, the materials for which are supplied by the Weather 

 Bureau. 



POINT REYES-SAN ANSELMO (CALIF.) SECTION (TELEPHONE), 



This line connects through the San Anselmo exchange of the 

 Pacific Telephone & Telegraph Co. with the Weather Bureau office 

 in San Francisco, and is used for transmission of meteorological 

 observations, vessel and wreck reports, forecasts, and storm warn- 

 ings. The Lighthouse and Coast Guard Services also have large 

 ne?d for its facilities, and the latter contributes extensively to its 

 maintenance. No commercial messages are handled. In February 

 a section of 13 miles of wire was transferred from poles of the 

 AVestern Union Telegraph Co, to those of the Pacific Telephone & 

 Telegraph Co., thus affording improved auditory and maintenance 

 conditions, copper wire having been substituted for galvanized-iron, 

 wire. Number of messages handled by the Weather Bureau, 1,481 ;. 

 cost of Weather Bureau of upkeep, $8.64. 



ALPENA-MIDDLE ISLAND-THUNDER BAY ISLAND (MICH.) SECTION (TELEPHONE). 



But little interruption occurred on either of these lines, except 

 during a portion of the winter and in June. This was caused by a 

 defective connection in the Alpena local exchange. 



During the year some repairs were made costing $97, but the ex- 

 tensive reconstruction contemplated as referred to in the last report 

 has been deferred, with the expectation of accomplishing it during 

 the coming autumn. 



By means of the two lines of 27^ miles in length, including 5^ 

 miles of submarine cable, marine interests are greatly benefited, as 

 they not only enable the bureau to display storm warnings, but 

 also to obtain accurate information regarding weather conditions 

 from each point for dissemination.
