The methods followed in testing the Ferre relift and the Richard 
relift were the same as those already described in the test of the Jami- 
son relift. In making the test of the Hine's relift the quantity of water 
was measured by means of a weir installed at the end of the flume. 
As the flow was rather turbulent,, the depth on the weir could not be 
read with great accuracy, and the results may be in error by 5 per 
cent. As the water was discharged vertically upward from the pump, 
the discharge gage could not be read as accurately as in the other 
test, but the readings are substantially correct and the final results 
satisfactory. 
Fuel oil used in these plants was Jennings crude, direct from the 
wells. A sample from the Richard relift had specific gravity 0.S975 
or 26.15° Baume at 100° F. 
DRAINAGE PUMPING PLANT AT PORT ARTHUR, TEX. 
This plant was installed to drain the city of Port Arthur, an area 
of approximately 2,175 acres. It is not an agricultural proposition 
and the capacity is far in excess of that required for farm lands. 
The pumping plant contains three units, each consisting of a vertical 
2-cylinder 100-horsepower oil engine direct-connected to a 48-inch 
screw pump. Two of the pumps were sold under a guaranty to de- 
liver 40,000 gallons per minute against a 5-foot lift and 26,000 gallons 
per minute against an 11-foot lift. The other pump was to deliver 
55,000 gallons per minute against a 5-foot lift. All operate at 257 
revolutions per minute. 
In the test of this plant, water measurements were made with a 
Pitot tube. The lift was determined bv means of gages set in suction 
and discharge basins. Fuel oil was measured by means of a spring 
balance. Readings of fuel were taken at 5-minute intervals. The oil 
used was sold as 28° Baume, weight 7.38 pounds per gallon. 
Tests were made on one high-lift and on the low-lift unit. In the 
course of the work of adjusting and testing the plant it was found 
that the blades were quite rough. When they were made smooth 
and sharp a marked improvement in capacity and duty was observed.
