being 14,753 boxes of one hundred pounds each, or upwards of 
120,000 salmon. The great production indicated by these figures 
must be regarded as resulting almost wholly from the natural 
breeding of the salmon. 
Among the trout-breeding establishments of Scotland is the 
famous one at Howietoun, near Stirling. Founded in 1873 by 
the late Sir James R. G. Maitland, it has been from the first, as 
now, the leading fish cultural establishment of Great Britain. It 
now offers for sale four species, the common European brown 
trout, the Loch Leven, the American brook trout and the rain- 
bow trout, at these rates per thousand: for ova, $2.40 for brown 
trout and Loch Levens, $3.60 for American brook trout and $4.80 
for rainbows; for yearlings prices ranging for the different 
species from $72 to $84. Two-year olds are to be had at $24 to 
$26.40 per hundred. These prices, which are doubtless about the 
same as those of other breeders, include transportation to any 
railway station in England, Wales or Scotland. The demand 
for these fish seems to be for the stocking of sporting waters. 
The success of the introduction of the two American species 
is regarded by the best authorities as still uncertain. 
NETHERLANDS. 
Prof. P. P. C. Hoek, scientific adviser of the Dutch govern- 
ment in fishery matters, has communicated interesting informa- 
tion regarding the Rhine salmon and its cultivation and other 
fish cultural subjects. 
The Dutch government engages in the artificial propagation 
of fish only indirectly and then only with reference to the salmon. 
Holland has only estuaries and a small part of the lower courses 
of the large rivers, whose sources are in other countries. There 
are no trouts, except a few rainbow and brown trouts reared in a 
private establishment and destined for restaurants in Amster- 
dam ;.there are no whitefish, except a migratory species (Core- 
gonus oxyrhynchus) ; there are no grayling. Of late the culture 
of carps and tenches has received the attention of some societies 
and private persons engaged in the fish trade. 
With regard to salmon culture it may be noted that the Dutch 
government expends $3,600 to $4,800 annually in the purchase 
of salmon fry from hatcheries at the headwaters of the Rhine in
