622  Repart  on  Implements  at  York. 
No.  2.  A coil  of  rope  (Lang’s  Patent)  which  had  been  in 
constant  use  for  2 years  and  2 months,  having  done  twice  as 
much  work  as  any  previous  rope  of  the  old  construction  under 
the  same  conditions. 
No.  3.  A coil  of  Lang’s  Patent  plough  steel  rope,  worn  down 
from  f to  ^ diameter,  having  done  twice  as  much  work  as  any 
previous  rope  of  the  old  construction  under  the  same  con- 
ditions. 
No.  4.  A coil  of  plough  steel  rope  (Lang’s  Patent),  5600 
yards  long,  weighing  6 tons,  made  for  the  Earl  of  Durham.  I 
was  informed  by  the  exhibitors  that,  since  the  introduction  of  the 
rope  in  1880,  it  has  been  applied  at  many  of  the  largest  colliery 
and  mining  works  in  the  country,  and  I am  permitted  to  intro- 
duce the  following  report  from  Mr.  Thomas  Watson,  the 
manager  of  the  Stores  Department  of  the  firm  of  Pease  and 
Partners,  Darlington  : — “ I have  pleasure  in  stating  that  your 
ropes  of  Lang’s  Patent  manufacture,  a great  many  of  which  are 
in  use  at  the  collieries  and  mines  here,  are  giving  entire  satis- 
faction, and  will  bear  a very  favourable  comparison  with  ropes 
from  other  makers  in  use  under  the  same  conditions.”  The 
manager  of  another  large  colliery  firm  states,  “ that  the  £ Lang’s 
Patent  steel  wire  rope,’  6200  yards  in  length,  which  was  supplied 
last  year,  has  worked  for  a period  of  fifteen  months  on  an  engine 
plane  which  has  several  curves,  and  is  of  varying  gradients,  to 
our  entire  satisfaction.”  For  agricultural  work  the  rope  has  not 
as  yet  been  extensively  manufactured.  Ploughing  ropes  have,  I 
believe,  been  sent  out  since  1880,  and  appear  to  have  given 
satisfaction.  There  is  one  other  point  that  should  be  named  as 
favourable  to  this  patent.  It  allows  of  the  use  of  wire  of  the 
hardest  class,  without  danger  of  breaking.  The  wire  that  is 
used  averages  125  tons  strain  per  square  inch  (i.e.  13J  wire 
gauge),  the  size  used  for  ploughing  ropes  is  equal  to  1850  lbs. 
breaking  strain. 
Roberts' s Rain-water  Separator. — This  apparatus  was  illustrated 
and  fully  described  by  Mr.  T.  F.  Jackson  in  his  Report  on 
Miscellaneous  Implements  at  Reading.  The  Judges  were  very 
favourably  impressed  with  the  ingenuity  of  the  apparatus,  the 
object  of  which  is  to  separate  the  water  first  collected  from  a 
roof — and  which,  varying  in  degree  according  to  the  situation  and 
period  of  drought  before  the  rain,  contains  impurities — from 
that  which  falls  after  the  roof  is  washed  clear  of  such  foreign 
materials.  It  is  not  necessary  to  repeat  the  description  or 
drawings.  It  is  sufficient  to  explain  that  the  apparatus  is 
suspended  on  a pivot,  and  is  divided  into  compartments,  in  such 
a manner  that  the  water  passes  into  the  waste-pipe  below  the 
machine,  until  such  time  as  the  water,  rising  to  a given  height  in
