The remains are chiefly of ferns, conifers, and cycadeae, but in the two former cases we have only cones and leaves. There have been discovered many pieces of wood, containing holes drilled by the teredo, and thus shewing that they had been long drifted about in the ocean before being entombed at the bottom.
It was expected that the double solution, by forming an insoluble compound, would prove an effective protection against the teredo. Experiments Nos. 4, 5, 6, and 8, however, proved the contrary to be the fact. The process, when well done, gave moderately satisfactory results against decay. A report by Mr.
The formation of the coast compelled them to pass eastward as they went on. But the currents of the Gulf flow in the opposite direction. Here there were steady winds from the east and the northeast. The ships were pierced by the teredo, which eats through thick timbers, and is so destructive that the seamen of later times have learned to sheath the hulls of their vessels with copper.
Holland came near perishing; its dikes were undermined by the teredo, and science is unable to discover the insect from which that mollusk derives, just as science still remains ignorant of the metamorphoses of the cochineal. The ergot, or spur, of rye is apparently a population of insects where the genius of science has been able, so far, to discover only one slight movement.
You've already done that yourself! You're going to Papeete to try to bid in the Valkyrie, and she's junk!" "Partly." Redell admitted. "She's been under water about two years and I suppose the teredo have digested her upper works by now; but they can be rebuilt quickly and without a great deal of expense." "How about her boilers? You'll have to retube them." "I don't think so.
The latter plan was very much the best in appearance, and the calculated cost was less than that of the pier of concrete piles, and only slightly more than that of creosoted piles, the latter being only of a temporary nature in any case, as it has been found that the protection afforded by creosote against the teredo is not permanent.
In this learned work the author discredits the popular ideas regarding the origin of the geese. Bot thair opinoun is vane. Our author no doubt here alludes to the ravages of the Teredo, or ship-worm, which burrows into timber, and with which the barnacles themselves are thus confused.
Above are the divine poet's larks and daisies, his incommunicable skies, his broad prospects of life and nature; and meanwhile our Teutonic teredo worms his way below, and offers to be our guide into an obscurity of his own contriving.
Carvajal made a formal protest before a notary who had accompanied him, and finding that the ships were suffering great injury from the teredo or worm, and their provisions failing, he sent them back to San Domingo, and set out on his return by land. Roldan accompanied him a little distance on horseback, evidently disturbed in mind.
Soundings indicated that this necessitated a pier 300 ft. long. It was further specified that the pier should be to some extent in keeping with the scale of the place being created there, and that a wooden pile structure would not be acceptable. Besides these esthetic conditions, wooden piles were rejected because the teredo, in this part of the Sound, is very active.
