"Distress Signals

"(a) When a vessel or seaplane on the water is in distress and requires assistance from other vessels or from the shore, the following shall be the signals to be used or displayed by her, either together or separately, namely

"(i) A gun or other explosive signal fired at intervals of about a minute.

"(ii) A continuous sounding with any fog-signalling appara

tus.

"(iii) Rockets or shells, throwing red stars fired one at a time at short intervals.

"(iv) A signal made by radiotelegraphy or by any other signalling method consisting of the group...

Morse Code.

in the

"(v) A signal sent by radiotelephony consisting of the spoken word 'Mayday'.

"(vi) The International Code Signal of distress indicated by N.C.

"(vii) A signal consisting of a square flag having above or below it a ball or anything resembling a ball.

"(viii) Flames on the vessel (as from a burning tar barrel, oil barrel, etc.).

"(ix) A rocket parachute flare or a hand flare showing a red light.

"(x) A smoke signal giving off a volume of orange-coloured smoke.

"(xi) Slowly and repeatedly raising and lowering arms outstretched to each side.

"NOTE.-Vessels in distress may use the radiotelegraph alarm signal or the radiotelephone alarm signal to secure attention to distress calls and messages. The radiotelegraph alarm signal, which is designed to actuate the radiotelegraph auto alarms of vessels so fitted, consists of a series of twelve dashes, sent in 1 minute, the duration of each dash being 4 seconds, and the duration of the interval between 2 consecutive dashes being 1 second. The radiotelephone alarm signal consists of 2 tones transmitted alternately over periods of from 30 seconds to 1 minute.

"(b) The use of any of the foregoing signals, except for the purpose of indicating that a vessel or seaplane is in distress, and the use of any signals which may be confused with any of the above signals, is prohibited.

"ANNEX TO THE RULES

"RECOMMENDATIONS ON THE USE OF RADAR INFORMATION AS AN AID TO AVOIDING COLLISION AT SEA

"(1) Assumptions made on scanty information may be dangerous and should be avoided.

"(2) A vessel navigating with the aid of radar in restricted visibility must, in compliance with Rule 16(a), go at a moderate speed. Information obtained from the use of radar is one of the circumstances to be taken into account when determining moderate speed. In this regard it must be recognised that small vessels, small icebergs and similar floating objects may not be detected by radar. Radar indications of one or more vessels in the vicinity may mean that "moderate speed" should be slower than a mariner without radar might consider moderate in the circumstances.

"(3) When navigating in restricted visibility the radar range and bearing alone do not constitute ascertainment of the position of the other vessel under Rule 16(b) sufficiently to relieve a vessel of the duty to stop her engines and navigate with caution when a fog signal is heard forward of the beam.

"(4) When action has been taken under Rule 16 (c) to avoid a close quarters situation, it is essential to make sure that such action is having the desired effect. Alterations of course or speed or both are matters as to which the mariner must be guided by the circumstances of the

case.

"(5) Alteration of course alone may be the most effective action to avoid close quarters provided that—

"(a) There is sufficient sea room.

"(b) It is made in good time.

"(c) It is substantial. A succession of small alterations of course should be avoided.

"(d) It does not result in a close quarters situation with other vessels.

"(6) The direction of an alteration of course is a matter in which the mariner must be guided by the circumstances of the case. An alteration to starboard, particularly when vessels are approaching apparently on opposite or nearly opposite courses, is generally preferable to an alteration to port.

"(7) An alteration of speed, either alone or in conjunction with an alteration of course, should be substantial. A number of small alterations of speed should be avoided.

"(8) If a close quarters situation is imminent, the most prudent action may be to take all way off the vessel."

Proclamation 3973-NINETEENTH DECENNIAL CENSUS OF THE UNITED STATES

SOURCE: Proclamation 3973 appears at 35 F.R. 5079, Mar. 26, 1970.

The Founding Fathers set forth in Article I of our Constitution the requirement that an ". '. . . Enumeration shall be made within three

Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years in such Manner as they shall by Law direct." Accordingly, the first Census was taken in 1790. The Nineteenth Decennial Census will be taken beginning April 1, 1970.

As our population has grown from the nearly four million counted in the first Census to over two hundred million, so the needs for the Census have expanded. Today, more than ever, we need reliable measures of the great changes which have occurred in the growth, location and characteristics of our people in their housing and activities.

Every American can be sure that there will be no improper use of the information given in the Census. Government officials and employees are forbidden by law to use information recorded on the Census form for the purposes of taxation, investigation, regulation, or for any other purpose whatsoever affecting the individual. Every employee of the Census Bureau is prohibited from disclosing information pertaining to any individual.

NOW, THEREFORE, I, RICHARD NIXON, President of the United States of America, do hereby declare and make known that under the law it is the duty of every person over eighteen years of age to answer all questions in the Census schedules applying to him and the family to which he belongs, and to the home occupied by him or his family.

The prompt, complete and accurate answering of all official inquiries made by Census officials is of great importance to our country. I ask all Americans to extend full cooperation to the 1970 Decennial Censusof Population and Housing.

IN WITNESS WHEREOF, I have hereunto set my hand this twenty-fourth day of March, in the year of our Lord nineteen hundred seventy, and of the Independence of the United States of America the one hundred ninety-fourth.

Proclamation 3989-RANDOM SELECTION FOR MILITARY SERVICE FOR REGISTRANTS WHO ATTAIN THE AGE OF NINETEEN DURING THE CURRENT YEAR

SOURCE: Proclamation 3989 appear at 35 F.R. 9989, June 18, 1970.

WHEREAS section 5(a) (1) of the Military Selective Service Act of 1967, as amended (50 U.S.C. App. 455 (a) (1)), provides that the selection of persons for training and service under that Act shall be made in an impartial manner without discrimination on account of race or color, under such rules and regulations as the President may prescribe; and

WHEREAS, by Executive Order 11497 and Proclamation 3945of November 26, 1969, I directed the establishment of a random selection sequence for all registrants who, prior to January 1, 1970, attained. their nineteenth year of age but not their twenty-sixth:

NOW, THEREFORE, I, RICHARD NIXON, President of the United States of America, do hereby proclaim the following:

That a random selection sequence will be established by a drawing to be conducted in Washington, D.C., on July 1, 1970, and shall be applied nationwide. The random selection method shall use 365 days to represent the birthdays (month and day only) of all registrants who, prior to January 1, 1971, shall have attained their nineteenth but not their twentieth year of age. The drawing, commencing with the first day selected and continuing until all 365 days are drawn, shall be accomplished impartially. The random selection sequence thus obtained shall, in accordance with the Selective Service Regulations, determine the order of selection of such registrants. The random sequence number thus determined for any registrant shall apply to him so long as he remains subject to induction for military training and service by random selection. Selection among registrants who have the same random sequence number, whether determined by the drawing of December 1, 1969, or that of July 1, 1970, shall be based upon the supplemental drawing conducted December 1, 1969, which determined alphabetically a random selection sequence by name.

IN WITNESS WHEREOF, I have hereunto set my hand this sixteenth day of June, in the year of our Lord nineteen hundred and seventy, and of the Independence of the United States of America, the one hundred and ninety-fourth.
