revived Magnolia pyramidata Pursh.* The geographical features 

 of the vicinity of Sisters' Ferry, and in fact the whole east side of 

 Effingham County, are rather peculiar, recalling those of the 

 Chattahoochee region of Decatur and Thomas counties. But 

 nothing definite is known about the geology of this county, and 

 the high water prevented me from getting much light on the 

 subject from the rocks along the river, f 



On July 31 I discovered something previously unknown to 

 science and entirely unexpected, viz., sand-hills on the Chatta- 

 hoochee River. These are located on the left or Georgia side in 

 Early County near Hilton. At all other easily accessible points 

 on the Chattahoochee there is not the slightest suggestion of sand- 

 hills, and I was informed that this particular area is only four or 

 five miles long. Where I crossed it it is about a mile and a half 

 wide. These sand-hills have the same general appearance as 

 many of those in Southeast Georgia, but their flora is not nearly 

 so rich in species, which is just what would be expected from their 

 remoteness from other similar areas. 



About the middle of August I went to River Junction, Florida, 

 about two miles south of the Georgia line, examined Ttnnion 

 taxifoluim % in its native haunts near there, and then spent nearly 

 two days walking up along the Flint River to Bainbridge, a dis- 

 tance of about thirty miles, trying to find this rare tree in Georgia.

In this particular I was unsuccessful, but the trip was by no means 

 unprofitable. In this extreme southwestern corner of the state 

 the phytogeographical features are rather complicated, and there- 

 fore interesting, but my time there was too short to make more 

 than a superficial examination. 



For the last fifteen miles of its course the Flint River (whose 

 junction with the Chattahoochee marks the corner of the state) 

 washes the northwestern base of an escarpment which is nearly 

 200 feet high in some places. This is a direct continuation of the

■f- This was just after one of the most disastrous 6oods ever known in South Caro- 

 lina, and the Savannah River at this point was then nine feet above low water mark and 

 still rising. I noticed however some fossiliferous rocks just above the water's edge. 



\ The odor of the bruised foliage of this tree is frequently mentioned, but I have 

 never seen it described. It reminded me of the odor of the foliage of Lycopenicum 

 more than anything else.
