Il8 FERNS 



ties of ferns. This collection is especially 

 interesting to fern students because of the 

 grouping of genera with correct labelling. 



The shape of this grotto is octagonal, meas- 

 uring 3 1 x 44 feet. Rugged and weather- 

 worn stones only were used in its construc- 

 tion. The inside work is the product of 

 Japanese workmen, although an increase of 

 height and other alterations have since been 

 made. The story of its making and manage- 

 ment belongs properly to the domain of 

 exotic fern culture, and is beyond the scope 

 of this volume.
