All these wonders I glimpsed in the space of a quarter of a mile, barely pausing, following Captain Nemo whose gestures kept beckoning me onward. Soon the nature of the seafloor changed. The plains of sand were followed by a bed of that viscous slime Americans call "ooze," which is composed exclusively of seashells rich in limestone or silica.Then we crossed a prairie of algae, open-sea plants that the waters hadn't yet torn loose, whose vegetation grew in wild profusion. Soft to the foot, these densely textured lawns would ha一ve rivaled the most luxuriant carpets woven by the hand of man. But while this greenery was sprawling under our steps, it didn't neglect us overhead. The surface of the water was crisscrossed by a floating arbor of marine plants belonging to that superabundant algae family that numbers more than 2,000 known species.I saw long ribbons of fucus drifting above me, some globular, others tubular: Laurencia, Cladostephus with the slenderest foliage, Rhodymenia palmata resembling the fan shapes of cactus.I observed that green-colored plants kept closer to the surface of the sea, while reds occupied a medium depth, which left blacks and browns in charge of designing gardens and flowerbeds in the ocean's lower strata.
约在四分之一海里的空间一内一，我没有停步，几乎不断地看到这些珍品。尼摩船长向我招手，我跟着他走。不久，脚下的土壤变了一性一质。接连细沙平原的是一片胶粘的泥地，单独由硅土或石灰贝壳构成，美国人管它叫“乌兹”。接昔我们跑过一段海藻地，它们是未经海水冲走的海产植物，繁殖力很强。这种纤维紧密的草坪，踩在脚下软一绵绵的，刁”以和人工织出的最柔软的地毯媲美。但是，不只我们脚下是绿草如茵，连我们头上也是一片翠绿。水面上轻飘飘地浮着一层海产植物，全部是取之不尽的海藻类，这类植物，我们已经知道的，至少有二千多种。我看见水中浮着很长的海带(有些作球形，有些作管状)、红花藻、叶子很纤细的薛苔、很像仙人掌的蔷薇藻。我注意到较近海面的一层是青绿一色一的海草，在更深一些的地方是红一色一的海草，黑一色一或赭一色一。的水草就在最深处，形成海底花园和草地。
