RADIO DIGEST — Illustrated February 16, 1921, WEATHER BUREAU AT SEA, NEW PLAN SHIPS TO RADIO REPORTS TO FLOATING STATIONS Great Value Seen in Ether Wave Service as Advanced by Ship Board WASHINGTON. — A plan to establish at least three sea-going weather bureaus in the North Atlantic depends upon whether a congressional appropriation of about $30,000 is forthcoming. This departure is based on the results achieved by the ich ineterologie.il ship Jacques Car now on a Pacific cruise. Details of the scheme were worked out by the United States shipping board and the weather bureau but money for the marine fore . s is needed. The shipping board is to furnish quarters, subsistence and Radio facilities Jfor two men on three of its trans-Atlantic vessels. The weather bureau will furnish and pay the skilled observers. A minimum estimate for a year's salaries is placed at $30,000. It is understood that Congress will be asked to make such an appropriation. Ships Floating Bureaus If the plans carry through, three government vessels will become floating weather bureaus where data received by Radio from other vessels on the North Atlantic will be compiled, and forecasts broadcast periodically, as the work done in branch offices ashore. Such a service, it is said, will be of great value to ships at sea, seaports and coastal regions. The weather bureau and the shipping board have been in co-operation for some time on marine meteorological reports. One new feature, just accomplished, is the scheme for all governmental vessels at sea to report as to the weather twice daily to the weather bureau. Masters of 300 Vessels Report The masters of more than 300 shipping board vessels recently began taking weather observations twice daily. This co-operation on the part of the meterological service and the shipping board will mean much to the weather forecasters ashore, as it will insure numerous regular reports from ships at sea in various localities. Orders to the masters of the shipping board fleet are to the effect that weather observations be taken daily at 7 a. m. and 7 p. m., 75th meridian time, and sent to the nearest naval Radio station as soon as possible, whenever the vessels are more than 100 miles at sea. Off the South Atlantic coast, when there are indications of hurricanes, observations are to be reported regardless of the distance off shore. Messages Handled Free The shipping board and the navy department have agreed to handle such messages free. The observations will consist of direction and'force of wind, state of weather, barometric pressure and pressure changes in past two hours, and notes on unusual conditions, such as signs of hurricanes or storms. Ships in the North Atlantic, Gulf of Mexico and Caribbean sea will transmit directly or through relays to the government observer, Washington. In the North Pacific, they will transmit to the government observer, San Francisco. RADIO TO BE TEACHER (Continued from page 1) whether Radio can be used to teach the children in the schools. Kadio Soon in Schools, Leader Says "The work that could thus be accomplished would be almost incredible. There is no question that Radio will in the near future be one of the most important factors in the educational system of this country. The sooner the National Education association starts the Radio survey and applies its conclusions, the better." (The National Education association includes almost every school teacher in the United States.) Executives of the Sunday school organization, whose members, it was said, number about 20,000,000, are to discuss the availability of Radio during their annual meeting here this month. "The utilization of Radio was discussed informally a few, weeks ago," said Dr. Hugh S. Magill, general secretary, headquarters Chicago. "It will doubtless be brought before the executive committee for discussion. It seems to be the general opinion that Radio could be used to great advantage in the Biblical education of children and of adults." The people of Illinois perhaps are foremost, it is said, in their attitude as to the use of Radio not only in the public but in Sunday schools. Impetus was given an inclination to investigate the feasibility of Radio as an educational instructor by the motion of R. L. Sandwick, principal of a township high school in Highland Park, 111., suburb of Chicago, during the recent annual meeting in Springfield of the Illinois State Teachers' association. Sandwick proposed that a broadcasting plant in Chicago be employed to place on the air during a certain school period the addresses or other utterances of personages who may be in this city. Sees Schools and Parents Nearer "My plan was and is twofold," Sandwick said. "Radio could be used, I am quite sure, to bring words of wisdom and amusement to the hundreds of thousands of children in the public schools of Illinois; it could be used, too, to acquaint their parents and other taxpayers with what the schools are doing for the children." That Radio could be applied to the education of children who, because of illness or other disability, may be unable to go to school, was suggested by Sandwick. "When the words of our leading men and women are brought directly to our children," said he, "when the opinions of president, governor, mayors, eminent preachers and lawyers, when the works of great musicians are carried vocally to the children in the high schools, the resultant educational values will be extremely large." The application of Radio as urged by Sandwick was to have been discussed in detail at the recent meeting in Bloomington, 111. (Normal, 111., a suburb), by members of the executive committee of the state teachers' association. Radio will also be an important phase of the program of superintendents in the association during a meeting this month in Bloomington. O. L. Manchester of Bloomington is president of the Illinois State Teachers' association, which numbers about 30,000. The sum of $10,000 has been appropriated by the association for the establishment of headquarters whose duties will be in part to investigate the practicability of Radio as an educational factor. Many of the public schools of Illinois already are equipped with receiving sets. (Recent research showed, too, that most of the pupils owned sets.) Schools not fitted with Radio receiving sets or unable financially to acquire them may, according to a proposed plan, buy them by means of funds raised through • public entertainments, fairs or the like. Illinois Sunday Schools Favor Flan Sunday schools in Illinois, whose enrollment, according to G. N. Burnie, general secretary of the state association, headquarters Chicago, is about 1,000,000 children and adults, are likely soon to adopt Radio in a manner similar to that proposed for the public schools. "The executive committee of the state association will undoubtedly act definitely this month as to the use of Radio to carry religious instruction," Mr. Burnie said. "The state association debated the feasibility of Radio a few weeks ago as the result of a growing demand for such an instrument of information." There are about 6,000 Sunday schools in Illinois, according to Burnie. If the plan of the association is put into practice a broadcasting station in Chicago may be retained to place on the air every Sunday, and perhaps one evening in the week, lessons pertaining to the Bible and allied subjects. If the vision of public and Sunday schools is fulfilled little Johnnie and Maggie may soon hear, say on Monday mornings after recess, the voice of a great singer or of a political pundit. And as Johnnie and Maggie, millions of 'em, cock their heads to listen, they will heed. Their teachers say so. Even so will it be with John and Margaret, well garbed and grave, as the voice of a famed minister or evangelist comes to them through the air, beseeching them to harken to the Good Word and to the call of the Spirit.
