filled in to a depth of several inches, the sod there having 
been previously removed and replaced after the filling. 
Drain pipes were also laid, thus improving the conditions 
and better adapting the soil at that point to the growing of 
herbaceous plants. 
Personal Investigations 
On July 6 I was granted leave of absence to continue my 
explorations in the Republic of Haiti. I left on that date, 
accompanied by an assistant, arriving again in New York on 
September 8. Finding it necessary to return to New York 
via Turks Islands, a stay of nine days was made at Grand 
Turk, where a collection was made; previous to this the col- 
lections at the Garden contained practically nothing from 
this island. <A detailed account of this exploration appeared 
in the Journau for November. 
The study and identification of the collections of living 
plants have been continued. Further studies of a systematic 
nature have been carried on in the grass family.
