(FIG. 26) On May 21, 1909, in walking from Leesburg to Okahumpka and back, I crossed a sluggish stream flowing into the west end of Lake Harris (which is connected with the Ocklawaha River), and was surprised to see that its water, instead of being coffeecolored as is usual in the lake region, was clear (like that of Lake Panasoffkee just described), which in peninsular Florida is a pretty Fig. 26.-Helena Run, looking west from railroad trestle about .4 miles from Leesburg and 2 from Okahumpka, Lake County.

Later in the da I was inforiied by an old resident of the neighborhood that this water comes from a limestone spring a few miles to the southwestward (Bug Sprinlg, near Okahumpka), but that in wet seasons when the lake is high this stream (Helena Run) flows the other way. and its waters find their way into the Gulf by way of the Withllaceoclhee iver.
