The radial canals are represented by wide gastric pouches, and may be absent, so that the tentacles arise directly from the stomach (Solmaridae).

The difficulty is solved by the provision of a complete system of minute intercellular spaces which form a continuous series of delicate canals between the cells, extending throughout the whole substance of the plant.

Similarly the obstructions offered to water communication by interruption through land or shallows are overcome by cutting canals or dredging out channels.

Through this part of its course the current of the river, except where restricted by floating bridges - at Feluja, Mussaib, Hillah, Diwanieh and Samawa - does not normally exceed a mile an hour, and both on the main stream and on its canals the jerd or oxbucket takes the place of the naoura or water-wheel for purposes of irrigation.

As main arteries for this circulation of water through its system great canals, constituting in reality so many branches of the river, connected all parts of Babylonia, and formed a natural means both of defence and also of transportation from one part of the country to another.

The first of these canals, taken off on the right bank of the river a little below Hit, followed the extreme skirt of the alluvium the whole way to the Persian Gulf near Basra, and thus formed an outer barrier, strengthened at intervals with watch-towers and fortified posts, to protect the cultivated land of the Sawad against the incursions of the desert Arabs.

In the time of the Arabs these were the chief canals, and the cuts from the main channels of the Nahr `Isa, Nahr Sarsar, Nahr Malk (or Nahr Malcha), and Nahr Kutha, reticulating the entire country between the rivers, converted it into a continuous and luxuriant garden.

Below the bifurcation the river of Babylon was again divided into several streams, and indeed the most famous of all the ancient canals was the Arakhat (Archous of the Greeks and Serrat and Nil of the Arabs), which left that river just above Babylon and ran due east to the Tigris, irrigating all the central part of the Jezireh, and sending down a branch through Nippur and Erech to rejoin the Euphrates a little above the modern Nasrieh.

Down to this point, the bed of the Euphrates being higher than that of the Tigris, the canals run from the former to the latter, but below this the situation is reversed.

The fact also that many of the most ancient of these ruins, like Ur, Lagash (Sirpurla), Larsa, Erech, Nippur, Sippara and Babylon, were situated on the banks of the great canals would indicate that the control of the waters of the rivers by a system of canalization and irrigation was one of the first achievements of civilization.

This ancient system of canalization was inherited from the Persians (who, in turn, inherited it from their predecessors), by the Arabs, who long maintained it in working order, and the astonishing fertility and consequent prosperity of the country watered by the Euphrates, its tributaries and its canals, is noticed by all ancient writers.

Boats could be conveyed over flat and easy portages from one river-basin to another, and these portages were subsequently transformed with a relatively small amount of labour into navigable canals, and even at the present day the canals have more importance for the traffic of the country than have most of the railways.

Groups of dwellings, such as are still to be seen on some of the small canals at Burano, clustered together along the banks of the deeper channels which traverse the lagoon islands and give access to the tide.

It is these channels which determined the lines of construction; the dwellings followed their windings, and that accounts for the extraordinarily complex network of calles and canals which characterizes modern Venice.

The smaller canals all serve as arteries to the Grand Canal.

The canals too were guarded by chains stretched across their mouths and by towers in some cases, as, for example, in the case of the Torresella Canal, which takes its name from these defence works.

The canals were crossed by wooden bridges without steps, and in the case of the wide Grand Canal the bridge at Rialto was carried on boats.

Ferries or traghetti for crossing the canals were also established as early as the 13th century; we find record of ferries at San Gregorio, San Felice, San Toma, San Samuele, and so on, and also of longer ferries to the outlying islands like Murano and Chioggia, or to the mainland at Mestre and Fusina.
