Several months ago The Pt^ant Worij) made a re(Hiosl for notes 

 on largfe trees. There are few trees of unusual size in Soutliern 

 Kentucky. The Tulip, or Yellow Poplar grows to a lai'ger size than 

 any other tree in Southern or Southeastern Kentucky. On the upper 

 Cumberland River it is not unusual to lind trees from 7 to 10 feet in 

 diameter. Amepican t^lms are from 5 to 6 feet in diamter in Warren 

 County. Silverleaf Po})lars -i to 5 feet. An unusual Ped Cedar 

 measures 4 feet, and a Black Oak 5 feet. An unusual Sycamore arow- 

 ing- near Barren River measures 25 feet in circumference. Neai- 

 Louisville, is a Chestnut feet in diameter and 8(i feet high. — Sadik

An instance of the individual a<laptations 1>\- which plants secure 

 necessary air or light under adverse conditions, was recently observed 

 at Watkins (xlen, N. Y. A long frond of the fern, ( '//.^foj/fr/-/'.s //////}/ fe/'</ , 

 was found growing partly within and partly without a crevice in the 

 rock: the pinnce of the })art in ordinary light formed the usual flat, 

 spreading frond, Imt the pinnce in the shade were turned shari)ly at 

 right angles to the plane of the frond in order to bring the u})per faces 

 perpendicular to the rays of light entering the crevice. This position 

 of these pinnce was fixed. The device was evidently successful, for 



that part of the plant growing in weak light was as green and healthy 

 in appearance as the part under normal conditions. — Minnie L.

A full length portrait of Linnanis was presented to the Philadel-
