General Development of the G.H.I. during 1958 
The number of copies printed, of the. "Machrichten für Seefahrer" (German 
Notices to Mariners) increased to 3.250. As regular enclosures, or in 
case of need, they contained: "Deckblätter zum Deuchtfeuerverzeichnis" 
(blocks showing amendments to the German list of lights); the "blue" lists 
showing the corrections in German charts; general directions and single 
instructions for sailing on the searched.fairways ("Zwangswege" - official 
routes); a list of these official routes and the booklet "Minengefährdete 
Gebiete" (dangerous áreas) with 10 two-coloured general maps. 
The 1 eleven parts of the "leuchtfeuerverzelehnis" (Ifv) (German list of 
lights) - I-IIIA,. II.IB-X) - could be replaced by new editions after one 
year’s run. Part XI (Pacific. Ocean, east side) went to the press; Part XII 
(Norwegian Sea, northern part, and North Polar Sea) is being prepared. 
At the request of shipping the 1959 edition of Part II ("Gewässer zwischen 
Nord- und Ostsee" - Baltic Entrances) will include information on the lights 
of the Göta Älf and of lake Vaner, 
In the "Nautischer Funkdienst" (N.F.) (German list of Radio Signals) 
the regulations concerning the position rapporting system newly introduced 
for the western North Atlantic and for the Indian Ocean were included. This 
new rapporting system aims at a centrally controlled safety action in case 
of distress at sea. The chapter: communication between aircraft and ships, 
was extended, too. The R/T Service for coastwise shipping contains now also 
information on Becca und Radar. 
By using different new kinds of techniques in the production of Charts, 
which save both time, and costs, the programme of renewal and extension 
mentioned in the Annual Report of the preceding year, could not only be 
kept in 1958 but even surpassed in part. 
Por the Baltic area two new charts covering’ the south and west coasts 
of Sweden appeared; in addition the coastal charts covering the north side 
of the Finnish Gulf were issued with extensive corrections. The special 
charts for the Belt Sea were renewed and some of them could be published 
already. The complete revision of the special charts covering the German' 
Bight was commenced in 1958, whereby some of the charts underwent also a. 
change as regards their extension. In this case, too, some of the revised 
charts could- be published already. By the issue of: new coastal charts for 
the southern North Sea, this area reaching from Scheveningen-southward and 
tor the west up to and including the English coast, could be completely 
covered uniformly by overlapping charts at a scale of 1:150.000, The 
publication, planned already for 1957« of further Becca charts for the 
North Sea - partly with the Becca grid of the English Chain - was accomplished 
with the issue of six hew Decca charts. 
The fishermen were supplied with a new fishery chart No, 256 PO "Gewässer
