  "These 
  tubers 
  grew 
  at 
  an 
  elevation 
  of 
  about 
  12,000 
  feet, 
  in 
  poor 
  and 
  stony 
  soil, 
  

   worked 
  with 
  wooden 
  plows. 
  The 
  Ullucus 
  are 
  sown 
  in 
  drills 
  like 
  potatoes, 
  after 
  which 
  

   they 
  are 
  molded 
  and 
  worked 
  with 
  hoes." 
  {Furlong.) 
  

  

  "The 
  melloca 
  is 
  half 
  a 
  runner; 
  its 
  shoots, 
  without 
  support, 
  send 
  out 
  roots 
  wherever 
  

   the 
  ground 
  is 
  touched. 
  Its 
  leaves 
  are 
  thick 
  and 
  fleshy; 
  from 
  being 
  large 
  and 
  spread- 
  

   ing, 
  they 
  become 
  erect 
  and 
  round 
  like 
  a 
  shell 
  in 
  the 
  fully 
  developed 
  plant. 
  The 
  

   flowers, 
  which 
  are 
  small 
  and 
  greenish, 
  spring 
  in 
  spikes 
  from 
  the 
  axil 
  of 
  the 
  leaves. 
  

   The 
  produce 
  of 
  the 
  melloca 
  consists 
  in 
  its 
  tubers, 
  which 
  in 
  their 
  native 
  country 
  attain 
  

   a 
  considerable 
  size. 
  They 
  are 
  yellow, 
  very 
  smooth, 
  full 
  of 
  starch, 
  and 
  appear 
  on 
  

   runners 
  proceeding 
  from 
  the 
  base 
  of 
  the 
  stem 
  and 
  tending 
  to 
  rise 
  to 
  the 
  surface 
  of 
  the 
  

   soil; 
  the 
  plant 
  must, 
  therefore, 
  be 
  pretty 
  well 
  earthed 
  up."

  "I 
  have 
  found 
  this 
  in 
  all 
  the 
  Andean 
  valleys 
  between 
  the 
  River 
  Apurimac 
  and 
  

   Potosi, 
  i. 
  e., 
  between 
  13° 
  and 
  19° 
  30' 
  south 
  latitude, 
  and 
  at 
  an 
  elevation 
  of 
  from 
  11,000 
  

   to 
  13,000 
  feet 
  above 
  the 
  level 
  of 
  the 
  sea. 
  It 
  is 
  extensively 
  cultivated 
  in 
  the 
  vicinity 
  

   of 
  the 
  populous 
  Bolivian 
  city 
  of 
  La 
  Paz 
  in 
  common 
  with 
  the 
  two 
  varieties 
  of 
  Oxalis 
  

   tuberosa 
  (Oca 
  augris 
  and 
  Oca 
  esanos). 
  It 
  (the 
  Oca 
  quina) 
  is 
  planted 
  between 
  the 
  25th 
  

   of 
  July 
  and 
  the 
  10th 
  of 
  August, 
  the 
  seed 
  employed 
  being 
  generally 
  the 
  smaller 
  tubers 
  

   unfit 
  for 
  food, 
  and 
  is 
  gathered 
  in 
  during 
  the 
  last 
  week 
  of 
  April. 
  It 
  will 
  be 
  recollected 
  

   that 
  these 
  two 
  periods 
  of 
  the 
  year 
  are 
  the 
  spring 
  and 
  autumn 
  in 
  the 
  Southern 
  Hemi- 
  

   sphere. 
  The 
  mode 
  of 
  cultivation 
  is 
  in 
  drills, 
  into 
  which 
  the 
  root 
  is 
  dropped 
  with 
  a 
  

   little 
  manure. 
  I 
  need 
  scarcely 
  state 
  that 
  at 
  the 
  great 
  elevation 
  of 
  La 
  Paz 
  (upward 
  

   of 
  12,000 
  feet) 
  the 
  climate 
  even 
  during 
  the 
  summer 
  season 
  is 
  severe, 
  scarcely 
  a 
  night 
  

   passing 
  over 
  without 
  the 
  streams 
  being 
  frozen 
  over, 
  the 
  sky 
  being 
  in 
  general 
  cloudless 
  

   at 
  all 
  periods 
  of 
  the 
  year 
  except 
  during 
  the 
  rainy 
  season 
  (December 
  to 
  March). 
  Mean 
  

   temperature 
  49°. 
  The 
  Oca 
  quina 
  (or 
  melloca) 
  is 
  chiefly 
  used 
  in 
  the 
  preparation 
  of 
  

   Chimo, 
  by 
  alternately 
  freezing 
  the 
  tubers 
  and 
  steeping, 
  by 
  which 
  they 
  are 
  changed 
  

   into 
  an 
  amylaceous 
  substance, 
  the 
  form 
  under 
  which 
  not 
  only 
  the 
  Ocas 
  but 
  the 
  common 
  

   potato 
  are 
  chiefly 
  employed 
  by 
  the 
  Indian 
  population; 
  an 
  operation 
  probably 
  intro- 
  

   duced 
  from 
  the 
  difficulty 
  of 
  boiling 
  the 
  unprepared 
  tuber 
  at 
  an 
  elevation 
  above 
  the 
  

   sea 
  where 
  the 
  point 
  of 
  ebullition 
  of 
  water 
  is 
  scarcely 
  high 
  enough 
  to 
  cook 
  raw 
  vege-

  "In 
  addition 
  to 
  these 
  statements 
  I 
  think 
  it 
  right 
  to 
  say 
  that 
  there 
  is 
  little 
  proba- 
  

   bility 
  of 
  this 
  plant 
  becoming 
  useful 
  as 
  a 
  garden 
  esculent. 
  Its 
  produce 
  will 
  probably 
  

   be 
  found 
  large 
  when 
  it 
  is 
  cultivated 
  in 
  the 
  manner 
  which 
  the 
  experience 
  already 
  

   gained 
  shows 
  to 
  be 
  necessary 
  to 
  it, 
  namely, 
  when 
  planted 
  in 
  the 
  beginning 
  of 
  

   March, 
  the 
  little 
  tubers 
  being 
  used 
  for 
  sets, 
  earthed 
  up 
  in 
  July, 
  and 
  harvested 
  in 
  

   November. 
  The 
  leaves 
  and 
  tubers 
  are 
  no 
  doubt 
  nutritive 
  but 
  so 
  full 
  of 
  an 
  insipid 
  

   and 
  somewhat 
  earthy 
  slime 
  that 
  whether 
  as 
  spinach 
  or 
  as 
  boiled 
  tubers 
  it 
  will 
  never 
  

   be 
  received 
  at 
  the 
  table 
  of 
  persons 
  of 
  taste."
