Page 365 - When it falls to the bottom of the vessel, it fixes its long pointed antennae firmly into the sand, and, with the assistance of the true feet, drags and pushes itself forward. This, however, may not be a natural mode of progression, but may be adopted in consequence of the artificial circumstances in which the animal is placed. Swimming is the natural mode of progression. It is amusing to see one of these animals resting, in an erect posture, on a branch of coralline, by means of its true thoracic...

From what has been said above, it will be seen that in order to count on continued good fisheries, the nature of the water should be kept unchanged as much as possible, and in fact it should in every way be made still more suitable for the various kinds of fish.

With the exception of those parts of the day when the herring is supposed to be asleep it is in constant motion, and its daily course, especially whilst near the coast, is entirely regular. It is well known now that the herrings generally keep quiet during the middle of the day and the middle of the night,...

Abdomen composed of six segments of which the five anterior ones are subequal and somewhat broader than the thorax ; last segment triangular, with rounded apex.

In the male the first antennae are about two-thirds...

Page 832 - Ki ver, asíate as 1853, the miners obtained a large supply of food from this source. At the present time no salmon enter these streams. It would be safe to estimate that onehalf the streams in this State to which salmon formerly resorted for spawning, have, for this purpose, been destroyed by mining. As mining is the more important industry, of course, for this evil there is no remedy...
Page 237 - He who knew the coast of Bohusliin 25 years ago, and now sees it again, will scarcely be able to refrain from tears. Then it presented an imposing appearance. From the sea itself rose massive walls and pillars supporting immense salting-houses and oil-refineries. Farther inland rich warehouses and busy workshops might be seen, as well as palatial residences of the merchants and neat cottages of the fishermen and workingmen.
