and persistence of white men to one of the best agricultural 

 districts. The soil is usually clay or clay loam and has been 

 recovered by clearing and a tairly good system of drainage. The 

 splendid farm buildings throughout and the prosperous appear- 

 ance of villages and towns show activit}-, thrift and success. 

 A few localities have become noted for apples and other fruits. 

 Some of the hnest apple orchards the writer has ever seen were 

 noticed east of Arkona. The position of the county as to water 

 front is unusually good. This, no doubt, as it becomes more 

 and more appreciated, will induce hundreds of people to build 

 cottages for suinmer residence on both lake and river shores. 

 In fact, this is already actively going on. To an outside observer 

 the suggestion is irresistible that the sand dunes at and near 

 Port Franks would make a fine Government reservation which 

 could be easily reached b)' electric railways from large cities.

CANADIAN SPECIES OF THALICTRUM. IV. 

 By Edward L. Greene. 



Continuing our study of the white-flowered meadow-rues 

 indigenous to Canada, a group of species which, if one regarded 

 nothing else but their stout white stamens, might be thrown 

 together as all one as these had been for a hundred years 

 formerly as T. Cornuti, later as T. polygamum we take up 

 next after T. zihellinuni of Sable Island, two others which, so 

 far as known, are of Newfoundland and Labrador. 



Thalictrum Terrae Novae. Stems neither stout nor 

 strongly angled or striate, glabrous throughout, copiously leafy 

 and very few-flowered, 2 feet high or more; basal leaves not seen, 

 the several cauline sessile, ample, deep-green above, glaucescent 

 beneath, all except the uppermost glabrous, but these with a 

 trace of scattered hairs beneath; terminal leaflets somewhat 

 round-obovate, \\ to lA inches long, of nearly equal breadth 

 above the middle, not deeply but very obtusely 3-lobed, the 

 medium lobe in the staminate plant much the largest, itself 

 usually 3-lobed (seldom so in the fertile plant), all lobes broader 

 than long, the leaflet as a whole always obtuse at base unless 

 obliquely cordate; lateral leaflets smaller, narrower in propor- 

 tion, mostly either .S-lobed or 2-lobed. a few obliquely oval and
