element 18 extends further and is longer than the second side element 20 thus at a lower end the lowermost portion 12 forms a point 24 where the first side element 20 and rear side 22 meet the outer edge 26 of the rear 22 slopes from sides 20 to 22 however as can be seen from the drawings the slope on the edge 26 is not straight and includes a slight indented shoulder 27 the lowermost portion 12 terminates at its upper end in the offset portion 16 the offset portion 16 is seen to advantage in side view in fig5 a and 5 b the offset portion 16 extends generally at right angles to the lowermost portion 12 and includes a pair of spaced upper and lower parallel frame members 28 and 30 respectively in use the frame members 28 30 cold be expected to rest generally horizontally at approximately ground level the lowermost stake portion 12 depends downwardly from one end of the offset portion 16 and the uppermost stake portion 14 extends generally upwardly from an opposing end of the offset portion thus the offset portion 16 directly above the lowermost stake portion 12 forms an open platform area serving as a hammer point 32 the end of the upper frame member 28 is rounded at the hammer point 32 that thus forms a target striking the hammer point 32 with an impact force will drive the lowermost stake portion 12 into the ground the lower frame member 30 includes on an outer side thereof a curled tongue extension 34 the extension 34 is open at an upper end and is thus able to receive a water supply pipe 36 or 38 as shown in fig5 a and 5 b the extension 34 is.
