motive equipment necessary or the operation of the pumping sta-
tion. In some cases it may he found advisable to use some form
of internal conlmbustic : engine. However. where electric trans-
mission lines are available it is often possible to take advantage of
much simplified design in tlie reclamation plan. since with electric
service it is possible to extend lines to Iinlts where tlhe chest ad-
vantage nmvy be taken of natural grades to :*.cure a more positive

consulted not only the publications mentioned but persons in the
state who are in positions to know what is correct and hest and
modern in the field of drainage and water control. Among those
who have bieen consulted aire Forrest 1. annning. agricultural
engineer for the Flo ida I Pwer ard ighL\ Co. Dr. 0. C. Bryan,
agronomnist and soil expert. and Frazier Rogers. agricultural en-
gineer. both of the Floridi College of Agriculture. 1. manning
and Ir. Bryan read and criticized the manuscript.
