EUCALYPTUS TREES, 73 
Messrs. A. W. Howitt, F. Webb, and D. Ballentine 
had there also large returns from their hop-fields. As 
an instance how large a revenue might be realized 
from forest land in various ways, quite irrespective of 
wood supply, I adduce the fact that the income ob- 
tained by the Forest Department of Hanover from the 
mere gathering of fruit—chiefly bleeberries—amount- 
ed to £21,750 during one of the late years. The Han- 
overian forests comprise an area equal to the county 
of Bourke, our metropolitan county, and occupy one 
seventh of the territory. Speaking of Hanover, let 
me add, that the laws promulgated this year in that 
country render it compulsory on each district to line 
its roads with trees, the widest distance allowed from 
tree to tree being thirty feet; similar laws were in 
force long since inother parts of Germany ; fruit-trees 
are among the trees chosen for these lines. Would it 
not therefore be advisable to naturalize along our forest 
brooks and in our shady vales such plants as the rasp- 
berry-bush, strawberry-plant, and others, which readily 
establish themselves ? In one of my exploring tours, 
when it fell to my lot to discover the remotest sources 
and tributaries of the River Yarra, and to ascend first of 
all Mount Baw Baw, I scattered the seeds of the large- 
fruited Canada blackberry along the alpine springs; 
and I have since learned that this delicious fruit is now 
established on the rivulets of that mountain. We may 
hear of equal successes of experiments which I else- 
where instituted. The truffie, though not an article 
of necessity, might be naturalized in many of our for- 
ests, especially in soil somewhat calcareous. Would 
any one imagine that during one recent year (1867) 
the quantity collected in France was valued at £1,-
