primitive state of things, we must artificially restore what 
has been taken away. 
This conviction led Baron BERLtPSCH to make a study 
of natural nesting-hollows and to construct a machine for the 
hollowing out of artificial nesting-boxes; it led him, moreover, 
to the cultivation of bushes, by cutting and partly also by 
grafting, which should tempt birds looking for suitable nesting- 
places to settle there. Of his success living examples may be 
send in the town-park of Cassel and the estate at Seebach, 
which Baron Berlepsch has converted into a real nesting colony. 
The most surprising success attained was when, after 
artificial nesting-boxes fixed on stakes had been placed on 
the colonies on the sand-hils of North Germany, not less 
than 90 7o of the same became inhabited, within the first 
year, by titmice up till that time unknown in the district. 
This attracted the attention of Iqnacz Daranyi too. 
Supported by the Hungarian Ministry of Commerce the 
first Hungarian Factory for the production of nesting-boxes 
has already been started, and there has appeared, from the 
pen of Titus Csorqey, published by the H. 0. C, a com- 
pendium of instructions dealing with the treatment and the 
use of nesting-boxes as well as with nesting bushes. 
On June 12, 1906 the Minister (No. 3686) ordered the 
Hungarian Central Office for Ornithology to present a scheme 
for the supplying of artificial nesting-boxes to the State 
forests (5 million acres). This work is now in hand. 
At the same period Count Albert Apponyi published his 
decree providing for the inclusion of birds' and trees' days 
in the scheme of work of elementary schools. 
Thus ends the history, for the present, of the International 
Convention of the protection of birds.
