Precisely, Ned: so that at 32 feet beneath the surface
of the sea you would undergo a pressure of 97,500 lb.
The water roared in his ears like the voice of Niagara, yet he heard the dull thunder of the volley and, rising again toward the surface
, met shining bits of metal, singularly flattened, oscillating slowly downward.
Filling my lungs with air, I dived beneath the surface
and swam through the inky, icy blackness on and on along the submerged gallery.
Once a little fish swam too near the surface
, and the kitten grabbed it in her mouth and ate it up as quick as a wink; but Dorothy cautioned her to be careful what she ate in this valley of enchantments, and no more fishes were careless enough to swim within reach.
One estimates it thirty miles, because the internal heat, increasing at the rate of about one degree to each sixty to seventy feet depth, would be sufficient to fuse the most refractory substances at that distance beneath the surface
It was not until I had passed the high peak and found the river that my eyes first discovered the pendent world, the tiny satellite which hangs low over the surface
of Pellucidar casting its perpetual shadow always upon the same spot--the area that is known here as the Land of Awful Shadow, in which dwells the tribe of Thuria.
Winding and twisting, but always tending upward, the tunnel led him nearer and nearer to the surface
, ending finally in a low-ceiled room, lighter than any that he had as yet discovered.
His efforts but served to accelerate the speed of the crocodile, and just as the ape-man realized that he had reached the limit of his endurance he felt his body dragged to a muddy bed and his nostrils rise above the water's surface
Instead a lusty cry for greater speed ahead urged the sinuous muscles gliding beneath the sleek brown hides; and when Muda Saffir rose to the surface
with a cry for help upon his lips Ninaka shouted back to him in derision, consigning his carcass to the belly of the nearest crocodile.
The smaller the sustaining surface
, the higher the speed.
The highest summit of all towers to a height of 22,606 feet above the surface
of the lunar disc.
By an inverse motion the base was approaching first; the lunar attraction was prevailing over the terrestrial; the fall toward the moon was beginning, almost imperceptibly as yet, but by degrees the attractive force would become stronger, the fall would be more decided, the projectile, drawn by its base, would turn its cone to the earth, and fall with ever-increasing speed on to the surface
of the Selenite continent; their destination would then be attained.
Hence it would continually be more and more advantageous to our humble-bee, if she were to make her cells more and more regular, nearer together, and aggregated into a mass, like the cells of the Melipona; for in this case a large part of the bounding surface
of each cell would serve to bound other cells, and much wax would be saved.
It could run with facility on the surface
of the water.
These experiences were very memorable and valuable to me -- anchored in forty feet of water, and twenty or thirty rods from the shore, surrounded sometimes by thousands of small perch and shiners, dimpling the surface
with their tails in the moonlight, and communicating by a long flaxen line with mysterious nocturnal fishes which had their dwelling forty feet below, or sometimes dragging sixty feet of line about the pond as I drifted in the gentle night breeze, now and then feeling a slight vibration along it, indicative of some life prowling about its extremity, of dull uncertain blundering purpose there, and slow to make up its mind.
