PLAN.TS OF SOUTHERN NEW jERvSEY. 357 



bud. With them, but not so definitely tufted, are the yellow 

 spikes of the Abama, the white, gummy-stemmed ToUeldia 

 and beds of the snowy, wooly heads of the Lophiola. There 

 are crimson Limodorums and pink Pogonias starring the grass 

 here and there, and where shallow, rusty, iron-stained, pools 

 are formed on either side of the rapid-flowing stream,; there 

 are solid masses of yellow Ultricularias, shining like beds of 

 gold in the sunlight. And in the deep water are white ix)nd lilies 

 and velvety leaves of the Golden Club, now gone to seed, erect 

 emerged spikes of J uncus militaris and Xyris congdoni and 

 great beds of Eriocaulon septangulare and Scirpiis subtcrminalis, 

 their leaves and stems ever swaying in the steady current. Truly 

 one of nature's flower gardens, and it stretches for miles, follow- 

 ing the course of the streams through the wilderness or pine, 

 cedar and white sand, now narrowing, now widening out into 

 broad stretches. Some seasons it is saturated with water and one 

 can only browse along the edges, at others the dried vegetation 

 forms a crust upon which one can walk with ease, though ever 

 mindful that beneath is an almost bottomless morass of mud and 

 decayed vegetation, so that it is safer in such spots to trust to 

 fallen cedar logs and dense clumps of rushes in shaping one's 

 course.
