14 ANNIVERSARY ADDRESS. 
tralia, Victoria, Queensland, and New South Wales, will be placed 
“before the public. As the method of producing the weather-map 
here isnoveland different tothat adopted in England and America, 
perhaps a few words of explanation may be devoted to it. In 
England, after the telegrams are received, a map is prepared by 
hand for lithographic printing, and 500 copies are printed by. 
3 p.m. each day, and distributed to subscribers, who pay a moderate 
sum for the information. Several. of the daily newspapers repro- 
duce portions of this map by engraving it on a block, and taking 
a cast from it, which is again stereotyped ; such at least was the 
method when I last heard. In America a stock of outline maps: 
of the States is kept ready to receive the weather information. 
Such parts of it as can be given in type are set up and printed 
on the outline map. The isobars are then put on a lithograph 
stone and printed on the map, which is then transferred to the 
stone containing isotherms, and there receives its fourth and last 
printing, and is ready for distribution early in the afternoon ; but 
it is not, so far as I am aware, reproduced by the newspapers. 
About 2,000 copies are distributed daily by post, and must of 
course take days in reaching some places. 
In Sydney the map is prepared in this way :—A block of metal 
of the size of the map, and one-eighth of an inch less in thickness 
than the height of ordinary type, has fixed upon it an electro 
outline of the coast and mountains of the eastern half of Aus-— 
tralia ; the electro is just of the thickness required to make it type 
high. At the position which each station occupies a hole is cut in 
the block, of the right size to receive the wind symbol, and the 
type necessary to prem. the —_ of — height - barometer, 
letter for rising or falling b the Spaces 
are also cut out to receive the list of temperature and rainfall, 
also for the explanatory matter. The rest of the block is flat, 
and, as I have stated, }-inch lower than the type. When the 
telegrams have been reduced and corrected, they are given on a 
convenient form to a compositor, who in a short time makes all 
the changes that are necessary to convert the figures of yesterday 
into those of to-day.
