This merely confirms the general conclusion which has been stated under the head of creosoting, that nothing but the impregnation with creosote, and plenty of it, is an effectual protection against the teredo. Numberless experiments have been tried abroad and in this country, and always with the same result.
No portion of the globe is more thickly inhabited, or affords, in proportion to its size, a greater amount of animal enjoyment than did this wave-tossed isle. On it were innumerable barnacles, several species of teredo, one of which, having its head shaped like a screw split into two equal portions, I believe to have been quite new.
And then you must consider taxes and depreciation, and sooner or later, if she lies in the mud long enough, the Teredo will eat her up; so it occurred to me that you might be glad to sell. She was built in 1883, but she was built to last " "Never built a cheap ship in my life and never ran 'em cheap," Cappy challenged proudly.
Everard Home, containing Observations on the Shell of the Sea Worm found on the Coast of Sumatra, proving it to belong to a species of Teredo; with an Account of the Anatomy of the Teredo navalis. The former he proposes to call the Teredo gigantea.
Such miserable paltry weaknesses and wickednesses, for in a servant of the Kingdom the feeling which suggests such a speech is wicked, are the moth holes in the garments of the Church, the teredo in its piles, the dry rot in its floors, the scaling and crumbling of its buttresses.
She had not been there long when it was discovered that her bottom was perforated by the teredo, and it appeared a short time before that a Dutch vessel had been entirely destroyed by them in less than two months. Rajah Laut, who had become heir to her great guns, no doubt hoped to obtain those of the Cygnet, as well as her stores and cargo, in the same manner.
Among the Acephala are to be named a large Cardium, also found on the Californian coast; Modiolus, two species; Mytilus; Mya, two species; and Teredo palmulatus: the latter, which is brought here by the ships, is very mischievous in the harbour, and attains to the length of two feet.
Then the young Crania adhered to the bared shell, grew and perished in its turn; after which the upper valve was separated from the lower before the Ananchytes became enveloped in chalky mud. Fossil and recent wood drilled by perforating Mollusca. Fossil wood from London Clay, bored by Teredina. b. Recent wood bored by Toredo. d. Shell and tube of Teredo navalis, from the same. c.
The result was, of course, that they lost more by capture than they gained by evading the regulation about the proper armament. 'His ship is not only of the very latest type but sheathed. Before copper sheathing was invented some generations later, the Teredo worm used to honeycomb unprotected hulls in the most dangerous way.
Quatrefages proposed to destroy the teredo in harbors by impregnating the water with a mineral solution fatal to them. Perhaps the labors of the coralline animals might be arrested over a considerable extent of sea-coast by similar means.
