12 MR. W. RUSHTON: STRUCTURE OF THE 
Juniperus macropoda came from Baluchistan. 
Juniperus recurva : area not exactly known but probably from the inner 
Himalayas in the Punjab. 
L wish to thank the Director of the Imperial Economist School of Forestry, 
Dehra Dun, for the information as to areas. 
In conclusion, Т beg to thank Professor Groom, of the Imperial College of 
Science and Technology, who suggested the work, for his help and criticism 
during the progress of the investigation.
