Rcmarhs on the recent Covference at Vienna on 
The organisation of radial stations has a wider scope, and 
is only suited ior extensive forests, such as those in Eastern 
Europe. The principle is that a central station is taken in the 
middle of a large forest, and then, along lines lying north, east, 
south, and west from that point, pairs of parallel stations are to 
be established, so as to trace the gradual diminution of forest 
influence in different directions. 
It is obvious that the maintenance of such a series of nine 
stations is only possible where the forests are in the hands of 
the State, and their management thoroughly centralised. 
Question III. 
To wJiat extent and Jwiv can meteorological ohscrvatories and stations include 
special observations for the purposes of agricultural meteorology in the 
sphere of their operations, without hindrance to their activity in other 
directions ? 
K. 22. " In consideration of the requirements of agricultural meteorology 
which have been already enumerated, the Conference is of opinion that, at 
least in the larger States, and where distinct organisations for the purpose do 
not exist, central institutions of a special character should be established. 
The objects of such institutions should be to perfect the methods of observa- 
tion, which are in many respects incomplete: to establish subordinate stations, 
or initiate their foundation : to support societies and private individuals in the- 
foundation and management of such stations : to control their operations, and 
to collect and discuss their observations. 
" Such special institutions should, however, always remain in connection 
with the general meteorological organisation of the country, in regard to the- 
critical selection of methods of observation and of the publications." 
This resolution also presupposes the existence of a powerful 
central scientific organisation, and any remarks to be made on 
this subject will more suitably be given further on. 
Question IV. 
Would it not he desirable, with a view to certain special observations which 
must be taken, such as, e.g., phenological observatio7is, to prepare a general 
Form of Instructions ? 
E. 23. "The Conference thinks it advisable to entrust the preparation of 
general instructions lor plienological observations to a special small Committee, 
consisting of three members. The preparation must be preceded by a careful 
examination and silting of the Instructions already existing in most countries. 
The business of this Committee should be conducted by correspondence, and 
care must be taken that the observations do not embrace too long a list of 
plants. They should deal, firstly, with cereals and forage plants ; secondly, 
with the more important forest- and fruit-trees; and lastly, with other plants 
of importance to agriculture, and with the i)henomcna of animal life." 
The subject of what are called in Germany " phenological 
phenomena," the phenomena of the plant and animal worlds 
which are connected with the return of the seasons, have for a 
long time attracted attention in several European countries.
