Hutchinson of New York, laid a short line from the Tarr Farm wells to the refinery, which passed over a hill, the oil being moved on the syphon principle, and a year later constructed another three miles long to the railway.
In the Le Bel-Henninger form a series of bulbs are connected consecutively by means of syphon tubes (b) and having platinum gauzes (a) at the constrictions, so that when a certain amount of liquid collects in any one bulb it syphons over into the next lower bulb.
It is possible that this represents the syphon or supplementary intestine of Capitellidae, which has been shown to develop as a groving of the intestine ultimately cut off from it.
The Glynsky form is simpler, having only one syphon tube; at the constrictions it is usual to have a glass bead.
Works required for this system are a syphon to pass the high level under the main canal near its head, bridges fitted with sluices where each canal passes under an embankment, and an escape weir at the tail of the system, just south of the desert point, to return surplus water to the river.
