CuitivatioH  of  Medicinal  Plants, 
Hyssopus  officinalis,  Melissa  officinalis,  Majoranum  hortense, 
Origanum  vulgare,  Tanacetum  vulgare,  etc.  Along  the  south  side 
of  the  slathouse  various  varieties  of  Vitis  vinifera  have  been  put 
in  to  afford  additional  shade.  Between  these  Citrullus  Colocynthis 
was  planted. 
The  slathouse,  a  structure  one  hundred  feet  long,  twenty  feet 
wide  and  seven  and  one-half  feet  high,  extends  along  the  east  side. 
A  collection  of  shade  loving  plants  has  already  been  obtained,  in- 
cluding Cimicifuga  racemosa.  Podophyllum  peltatum,  Hydrastis 
canadensis,  Geranium  maculatum,  Sanguinaria  canadensis,  Spigelia 
marilandica,  Aspidium  species,  Cypripedium  spec,  and  many  others. 
A  long  bed  is  laid  out  along  the  front  of  the  house  and  here  different 
species  of  the  following  genera  have  been  planted :  Luffa,  Momor- 
dica,  Citrullus,  Convolvulus,  Bryonia,  Cucurbita  and  Cucumis.  In 
addition  tO'  these  climbers,  such  perennials  as  Clematis,  Humulus, 
Ampelopsis,  Solanum,  Wistaria,  Aristolochia  and  Pueraria  species 
are  to  be  found.  The  entire  length  of  the  bed  is  bordered  with 
Digitalis  species  and  there  is  also  a  fine  display  of  Cannabis  gigantea, 
Cannabis  american,  Foeniculum  vulgare  and  Zea  Mays  varieties. 
The  largest  portion  of  the  garden  is  laid  out  into  the  rectangular 
plots  previously  referred  to.  Of  these  the  following  are  deserving 
of  special  mention : 
Plot  No.  4  is  planted  with  Conium  maculatum.  This  plant  has 
done  remarkably  well.  Several  of  the  specimens  now  in  blossom 
have  attained  a  height  of  over  four  feet. 
Plot  No.  6  contains  Ricinus  communis  var.  minor  and  Ricinus 
communis  var.  major  as  well  as  a  number  of  other  species.  The 
seed  sold  as  drug  often  appears  to  be  a  mixture  of  seed  from  the 
different  species  of  Ricinus. 
Plots  Nos.  8,  12,  13,  16,  28,  48,  49,  61  and  62  are  filled  with 
different  varieties  and  species  of  Digitalis  and  it  is  hoped  that  some 
work  can  soon  be  done  concerning  the  factors  which  influence  the 
potency  of  the  official  drug. 
Plot  No.  14  contains  Aconitum  Napellus,  A.  Lycotonum  and  A. 
Fischerii,  also  Delphinium  Staphisagria  and  other  species  of 
Delphinium. 
In  Plot  No.  17  may  be  found  capsicum  frutescens  and  other 
species  of  capsicum. 
Plot.  No.  20. — Sinapis  nigra  and  Sinapis  alba.
