  cannot even recollect the Crimean Winter; as it was called then; and well
  for   you   you   cannot;   considering   all   the   misery   it   brought   at   home   and
  abroad。      You     cannot;    I  say;  recollect   the   Crimean      Winter;   when     the
  Thames was frozen over above the bridges; and the ice piled in little bergs
  ten to fifteen feet high; which lay; some of them; stranded on the shores;
  about London itself; and did not melt; if I recollect; until the end of May。
  You   never   stood;   as   I   stood;   in   the   great   winter   of   1837…8   on   Battersea

  Bridge; to see the ice break up with the tide; and saw the great slabs and
  blocks   leaping   and   piling   upon   each   other's   backs;   and   felt   the   bridge
  tremble with their shocks; and listened to their horrible grind and roar; till
  one got some little picture in one's mind of what must be the breaking up
  of an ice…floe in the Arctic regions; and what must be the danger of a ship
  nipped in the ice and lifted up on high; like those in the pictures of Arctic
  voyages which you are so fond of looking through。                  You cannot recollect
  how that winter even in our little Blackwater Brook the alder stems were
  all   peeled   white;   and   scarred;   as   if   they   had   been   gnawed   by   hares   and
  deer; simply by the rushing and scraping of the ice;a sight which gave
  me again a little picture of the destruction which the ice makes of quays;
  and stages; and houses along the shore upon the coasts of North America;
  when   suddenly   setting   in   with   wind   and   tide;   it   jams   and   piles   up   high
  inland; as you may read for yourself some day in a delightful book called
  Frost and Fire。       You recollect none of these things。           Ice and snow are to
  you    mere    playthings;     and   you    long   for   winter;   that   you   may    make
  snowballs and play  hockey and skate  upon the  ponds; and eat   ice like  a
  foolish boy till you make your stomach ache。                 And I dare say you have
  said; like   many  another boy;  on   a bright   cheery  ringing frosty  day;  〃Oh;
  that   it   would   be   always   winter!〃    You   little   knew   for   what   you   asked。
  You   little   thought   what   the   earth   would   soon   be   like;   if   it   were   always
  winter;if one sheet of ice on the pond glued itself on to the bottom of the
  last sheet; till the whole pond was a solid mass;if one snow…fall lay upon
  the top of another snow…fall till the moor was covered many feet deep and
  the snow began sliding slowly down the glen from Coombs's; burying the
  green fields; tearing the trees up by their roots; burying gradually house;
  church; and village; and making this place for a few thousand years what it
  was many thousand years ago。              Good…bye then; after a very few winters;
  to bees; and butterflies; and singing…birds; and flowers; and good…bye to all
  vegetables; and fruit; and bread; good…bye to cotton and woollen clothes。
  You would have; if you were left alive; to dress in skins; and eat fish and
  seals; if any came near enough to be caught。              You would have to live in a
  word; if  you   could   live  at   all;  as   Esquimaux   live  now  in Arctic   regions;
  and as people had to live in England ages since; in the times when it was

  always      winter;   and   icebergs    floated    between     here   and   Finchampstead。
  Oh     no;   my    child:    thank     Heaven     that   it  is  not  always     winter;    and
  remember   that   winter   ice   and   snow;   though   it   is   a   very   good   tool   with
  which to make the land; must leave the land year by year if that land is to
  be fit to live in。
  I said that if the snow piled high enough upon the moor; it would come
  down the glen in a few years through Coombs's Wood; and I said then you
  would have a small glacier heresuch a glacier (to compare small things
  with great) as now comes down so many valleys in the Alps; or has come
  down all the valleys of Greenland and Spitzbergen till they reach the sea;
  and     there   end   as   cliffs  of   ice;  from     which    great    icebergs    snap    off
  continually; and fall and float away; wandering southward into the Atlantic
  for many a hundred miles。             You have seen drawings of such glaciers in
  Captain Cook's Voyages; and you may see photographs of Swiss glaciers
  in   any   good   London   print…shop;   and   therefore   you   have   seen   almost   as
  much   about   them   as   I   have   seen;   and   may   judge   for   yourself   how   you
  would like to live where it is always winter。
  Now you must not ask me to tell you what a glacier is like; for I have
  never   seen   one;   at   least;   those   which   I   have   seen   were   more   than   fifty
  miles away; looking like white clouds hanging on the gray mountain sides。
  And   it   would   be   an    impertinencethat   means   a        meddling   with   things
  which   I   have   no   businessto   picture   to   you   glaciers   which   have   been
  pictured so well and often by gentlemen who escape every year from their
  hard   work   in   town   to   find   among   the   glaciers   of   the   Alps   health   and
  refreshment;       and    sound     knowledge;       and    that   most    wholesome        and
  strengthening of all medicines; toil。
  So you must read of them in such books as Peaks; Passes; and Glaciers;
  and   Mr。   Willes's   Wanderings   in   the   High   Alps;   and   Professor   Tyndall's
  different     works;    or   you    must    look   at  them    (as   I  just   now    said)   in
  photographs   or   in   pictures。      But   when   you   do   that;   or   when   you   see   a
  glacier for yourself; you must bear in mind what a glacier meansthat it is
  a river of ice; fed by a lake of snow。              The lake from which it springs is
  the   eternal   snow…   field   which   stretches   for   miles   and   miles   along   the
  mountain tops; fed continually by fresh snow…storms falling from the sky。

  That snow slides off into the valleys hour by hour; and as it rushes down is
  ground and pounded; and thawed and frozen again into a sticky paste of
  ice;  which   flows   slowly  but surely  till it   reaches the   warm  valley  at   the
  mountain foot; and there melts bit by bit。 The long black lines which you
  see   winding   along   the   white   and   green   ice   of   the   glacier   are   the   stones
  which have fallen from the cliffs above。              They will be dropped at the end
  of the glacier; and mixed with silt and sand and other stones which have
  come   down   inside   the   glacier   itself;   and   piled   up   in   the   field   in   great
  mounds; which are called moraines; such as you may see and walk on in
  Scotland many a time; though you might never guess what they are。
  The river which runs out at the glacier foot is; you must remember; all
  foul and   milky  with the   finest   mud;   and that   mud   is the   grinding   of   the
  rocks over which the glacier has been crawling down; and scraping them
  as it scraped my bit of stone with pebbles and with sand。                  And this is the
  alphabet; which; if you learn by heart; you will learn to understand how
  Madam How uses her great ice…plough to plough down her old mountains;
  and   spread   the   stuff   of   them   about   the   valleys   to   make   rich   straths   of
  fertile   soil。   Nay;   so   immensely   strong;   because   immensely   heavy;   is   the
  share of this her great ice…plough; that some will tell you (and it is not for
  me to say  that they  are wrong) that   with it   she has ploughed out all   the
  mountain   lakes   in   Europe   and   in   North   America;   that   such   lakes;   for
  instance; as Ullswater or Windermere have been scooped clean out of the
  solid rock by ice which came down these glaciers in old times。                       And be
  sure of this;  that next   to Madam  How's   steam…pump   and   her   rain…spade;
  her great ice…plough has had; and has still; the most to do with making the
  ground on which we live。
  Do   I   mean   that   there   were   ever   glaciers   here?  No;   I   do   not。   There
  have   been   glaciers   in   Scotland   in   plenty。    And   if   any   Scotch   boy   shall
  read this book; it will tell him presently how to find the marks of them far
  and wide over his native land。           But as you; my child; care most about this
  country  in
