  "The 
  two 
  nurseries 
  respoiisible 
  for 
  the 
  original 
  eastern 
  introduc- 
  

   tion 
  of 
  the 
  scale 
  are 
  near 
  Burlington. 
  N. 
  J., 
  and 
  Little 
  Silver, 
  N. 
  J., 
  

   the 
  one 
  on 
  the 
  Delaware 
  Kiver 
  and 
  the 
  other 
  near 
  the 
  Atlantic 
  coast. 
  

   The 
  scale 
  was 
  introduced 
  into 
  these 
  two 
  nurseries 
  in 
  the 
  same 
  way. 
  

   Either 
  in 
  1886 
  or 
  1887, 
  in 
  the 
  endeavor 
  to 
  secure 
  a 
  thorough 
  curcu- 
  

   lio-proof 
  plum, 
  both 
  of 
  these 
  nurseries 
  introduced 
  from 
  California 
  

   an 
  improved 
  Japanese 
  variety, 
  the 
  Kelsey. 
  obtained 
  from 
  the 
  San 
  

   Jos6 
  district. 
  We 
  have 
  the 
  statement 
  from 
  the 
  proprietors 
  of 
  one 
  of 
  

   the 
  nurseries 
  that 
  the 
  plum-trees 
  in 
  question 
  were 
  secured 
  in 
  the 
  

   spring 
  of 
  1887 
  from 
  San 
  Jose, 
  California, 
  and 
  were 
  shipped 
  through 
  

   the 
  agency 
  of 
  the 
  Missouri 
  Nursery 
  Compan}'. 
  which 
  acted 
  in 
  this 
  

   instance 
  apparently 
  as 
  a 
  mere 
  transmitting 
  agent. 
  The 
  trees 
  were 
  

   uncpiestionably 
  thoroughly 
  infested 
  when 
  received, 
  did 
  not 
  thrive, 
  

   and 
  in 
  both 
  cases 
  most 
  of 
  them 
  were 
  ultimately 
  taken 
  out 
  and 
  de- 
  

   stroyed. 
  The 
  stock, 
  however, 
  had 
  been 
  multiplied 
  by 
  nursery 
  

   methods, 
  and 
  from 
  the 
  original 
  stock 
  and 
  that 
  subsequently 
  obtained 
  

   the 
  scale 
  spread 
  more 
  or 
  less 
  completely 
  throughout 
  both 
  of 
  the 
  nur- 
  

   series 
  in 
  question. 
  

  

  "In 
  the 
  case 
  of 
  one 
  of 
  the 
  nurseries 
  the 
  scale 
  spread 
  to 
  bearing 
  

   pear-trees, 
  and 
  from 
  these 
  had 
  spread 
  yearly 
  to 
  neighboring 
  nursery 
  

   trees. 
  In 
  the 
  other 
  nursery, 
  fruit 
  growing 
  is 
  quite 
  an 
  important 
  

   feature, 
  and 
  the 
  scales 
  had 
  spread 
  early 
  from 
  the 
  introduced 
  plum- 
  

   trees 
  to 
  bearing 
  fruit 
  trees, 
  and 
  also 
  infested 
  low 
  shrubs 
  and 
  plants, 
  

   particularly 
  currants 
  of 
  both 
  the 
  lilack 
  and 
  white 
  varieties. 
  It 
  spread 
  

   finally 
  more 
  or 
  less 
  thoroughly 
  throughout 
  large 
  blocks 
  of 
  nursery 
  

   stock. 
  Both 
  of 
  these 
  firms, 
  when 
  the 
  nature 
  of 
  the 
  infestation 
  was 
  

   brought 
  to 
  their 
  attention 
  and 
  the 
  seriousness 
  of 
  the 
  damage 
  they 
  

   were 
  doing 
  was 
  made 
  apparent 
  to 
  them, 
  undertook 
  measures 
  to 
  ex- 
  

   terminate 
  the 
  scale. 
  One 
  of 
  the 
  nursery 
  companies 
  was 
  particularly 
  

   prompt 
  and 
  thorough 
  in 
  its 
  efforts 
  in 
  this 
  direction, 
  and 
  deserves 
  

   great 
  credit 
  for 
  the 
  manner 
  in 
  which 
  it 
  undertook 
  the 
  work; 
  the 
  

   other 
  was 
  for 
  a 
  time 
  dilatory 
  and 
  seemingly 
  indifferent, 
  but 
  was 
  

   forced 
  by 
  the 
  necessities 
  of 
  its 
  business 
  and 
  by 
  pu))lic 
  opinion 
  to 
  

   adopt 
  similar 
  remedial 
  measures."
