"  The  Propagation  of  Medicinal  Plants,"  a  thesis  presented  to  the 
Purdue  University  toward  the  degree  of  Master  of  Science,  pub- 
lished in  the  Bulletin  of  Torrey  Botanical  Club,  No.  41,  pp.  105-129, 
March  23,  1914. 
This  paper  in  a  degree  covers  the  entire  subject  of  medicinal 
plants  in  five  divisions,  as  follows : 
Commercial  samples  and  shipment  of  drugs. 
Crude  drug  merchants. 
Individuals  living  in  or  near  the  producing  regions  or  others 
carrying  on  investigations  of  similar  plants. 
Public  and  private  botanical  gardens,  experimental  stations,  and 
other  institutions. 
Commercial  seedsmen  and  nurserymen. 
The  paper  includes  germination  tests,  and  a  list  of  commercial 
seedsmen  and  nurserymen  from  whom  seeds  and  plants  may  be 
obtained. 
The  writer  states  that  open-field  methods  of  seeding  have  been 
found  impracticable  and  in  many  cases  impossible  for  many  medicinal 
plants. 
The  author  is  of  the  opinion  that  more  data  are  required  upon 
the  propagation  of  the  most  important  drug  plants  which  are  adapted 
in  this  country;  that  methods  would  have  to  be  developed  to  suit 
conditions  of  soil  and  climate  and  at  the  same  time  be  varied  to  meet 
the  purposes  of  the  work. 
He  believes  that  commercial  drugs  might  be  possible  under  a 
system  which  would  be  worthless  for  experimental  work  or  plant 
breeding  improvements. 
The  paper  will  be  found  instructive  to  all  who  may  be  interested 
in  the  subject.
