Dec. 6.] THE NEW ZEALAND GAZETTE. 4457

The following information is given:-
Typhoon and Continental Depression Signals:
(a.) Position of centre; by four symbols at one yard-arm.
(b.) Direction of motion and velocity of centre, and the time; by three symbols at the other yard-arm (Tables 1, 2, and 3).
Gale Signals:
(c.) The region threatened, the direction from which the gale is expected, and the time; by three symbols at one yardarm (Tables 3 and 4).

Conditions at 2 p.m. to-day indicated a typhoon in about latitude 18° N., and longitude 109° E., travelling W.N.W. at the rate of 8 to 12 miles per hour.

Conditions at 6 a.m. to-day indicated a typhoon filling up in about latitude 26° N. and longitude 119° E. Direction of motion unknown.

Conditions at 2 p.m. yesterday indicated a continental depression in about latitude 30° N. and longitude 121° E., travelling E. or E.S.E.

Conditions at 6 a.m. yesterday indicated a N.E. gale in the Formosa Channel.

Explanation of the Signals.
The two upper signals of group (a) indicate the latitude, and the two lower symbols the longitude of the centre of the typhoon or depression in degrees, as nearly as can be ascertained from the information available. Only the tens and units of the longitude are given-thus, 09 indicates longitude 109° E.
The upper symbol of group (b) indicates the direction in which the typhoon or depression is travelling (Table 1). The middle symbol of group (b) indicates the velocity at which the centre of the typhoon is travelling. Alternatively it may indicate certain conditions, or a continental depression. In such cases no velocity is given.
The lowest symbol of group (b) indicates the time at which the centre was in the position signalled.
The upper symbol of group (c) indicates the region threatened; the middle symbol the direction from which the gale is expected, and the lowest symbol the time at which gale conditions were first indicated.
Caution.-Under the most favourable circumstances the position signal indicates only the degree of latitude and longitude nearest to the estimated position of the centre. When the centre is far from any reporting station, or when telegraphic reports are lacking, the position signalled may be as much as 2° in error, both in latitude and longitude, and the velocity and direction of motion will then be in error by corresponding amounts.
It should be particularly noted that the velocity signalled is the mean for the previous 16 or 24 hours.

These indicate the direction in which a typhoon or depression is travelling, or the direction from which a monsoon gale is expected.
