The public hatchery also gives an excellent opportunity for the introduction of good stock among farmers who would be too shiftless to acquire it by ordinary methods. The old adage that a little knowledge is a dangerous thing is nowhere better illustrated than in the scientific phases of poultry feeding.
Here they assembled for the best part of each day; the talk ranged over literary and publishing matters of mutual interest, and Kipling promptly labelled the room "The Hatchery," from the plans and schemes that were hatched during these discussions.
Passing the Hatchery we were only a few more minutes in reaching Tallac House, the first to complete the auto-trip this season. Except for a few short stretches of scarcely completed road it is in excellent condition, and the road gang now at work will have all the rough portions smoothed down in a few days.
This water should be poured off and fresh added till the superfluous milt is washed away, when the ova should be left in the water till they separate, which will be in about twenty minutes or half an hour. The fertilized ova thus obtained may either be laid down in artificially protected hatching beds, or may be transferred to a hatchery.
Third, the Chinese incubator, much on the principle of the Egyptian hatchery, but run in the room of an ordinary house, heated with charcoal braziers and used only for duck eggs. I have no accurate information on the results of the Chinese method, and as it is not used for hen eggs, we will confine our attention to the first two processes only.
There is some research work done also, and at the present moment Professor Jacques Loeb is doing some wonderful work over there on fish hybridization. We are entirely distinct organizations, one being a summer school and the other being a government marine hatchery with a biological laboratory attached.
But herring and salmon trout did not satisfy us; we wanted brook trout, too. And so one day a shipment of babies arrived from the hatchery at Sault Ste. Marie, and thus we first became acquainted with the habits of infant fishes, and learned something of their needs and the methods of their foster-parents. One after another our neighbors introduced themselves, each in his own way.
The latter proceeding, of course, requires a hatching house specially built and arranged, and as this is outside the scope of the present work, I would refer my readers to larger works upon the subject, such as An Angler's Paradise, by J. J. Armistead. Of course, by using a hatchery a large number of the eggs will be saved, ninety per cent. of them should hatch out.
The majority of such machines are probably too much ventilated. In a large and properly constructed hatchery, such as is discussed in the last section of this chapter, the entire composition of the air, as well as its movement, is entirely under control.
Instantly the measurer called out the length and the professor noted it down, the hatchery foreman famous for his expertness in judging the weight of a fish calling out the weight to be recorded.
