This allows a hose near the ground-line, a tube with a the atmospheric pressure to reach the water, gage-glass, means for making a water joint and in the case of the lower bulb 5 also allows on said glass, provided with a connection for the access of the water to the said bulb. 15 a hose near the ground, a graduated staff and The operation is as follows: The tubes 4. means to adjust the tube (with the glass) and and 8 are filled with water, as shown, after secure it to said stafl, and a hose-pipe conthe hose '7 has been connected. Said hose necting the two tubes, said hose and tubes to may be one hundred or two hundred feet, as be filled with water, making an instrument the operator may require. The valve 6 of 20 especially adapted for the use of the farmer each sphere is released, the tube 4 is forced in grading his ditches for irrigating. It is in the ground, and the level is taken on the simple in construction and operation and is glass gage. The operator wishing to have a accurate.
