  this about if he could。
  Tom kept on with his powder experiments。 Mr。 Damon helped him; for
  that gentleman had succeeded in putting the affairs of the wholesale drug
  business     on   a  firm    foundation;     and   there   was    no   more    trouble    about

  TOM SWIFT AND HIS BIG TUNNEL
  getting   the   supplies   of   cinchona   bark   to   market。   The   natives   seemed   to
  have taken kindly to the eccentric man; or perhaps it was the reputation of
  Tom Swift and his electric rifle that induced them to work hard。
  It must not be supposed that Professor Bumper was idle all this while。
  He came and went at odd times; accompanied by his little retinue of
  Indians;   a   guide   and   a   native   cook。   He   would   come   back   to   the   tunnel
  camp;   where   he   made   his   headquarters;   travel   stained;   worn   and   weary;
  with disappointment showing on his face。
  〃No luck;〃 he would report。 〃The hidden city of Pelone is still lost。〃
  Then   he   would   retire   to   his   tent;   to   pour   over   his   note…   books;   and
  make a new translation of the inscription on the golden plates。 In a day or
  so; refreshed and rested; he would prepare for another start。
  〃I'll find it this time; surely!〃 he would exclaim; as he marched off up
  the mountain trail。 〃I have heard of a new valley; never before visited by a
  white man; in which there are some old ruins。 I'm sure they must be those
  of Pelone。〃
  But in a week or so he would come back; worn out and discouraged
  again。
  〃The   ruins   were   only   those   of   a   native   village;〃   he   would   say。   〃No
  trace of an ancient civilization there。〃
  The    professor     took   little  or  no   interest   in  the   tunnel;   though     he
  expressed   the   hope   that   Tom   and   his   friends   would   be   successful。   But
  industrial pursuits had no charm for the scientist。 He only lived to find the
  hidden city which was to make him famous。
  He heard the story of the queer shaft leading down into the bore under
  the mountain; and; for a time; hoped that might be some clue to the lost
  Pelone。 But; after an examination; he decided it was but the shaft to some
  ancient mine which had not panned out; and so had been abandoned after
  having been fitted with a balanced rocky door; perhaps for some heathen
  religious rite。
  There     seemed     to  be   no   further    trouble   among      the  Indian    tunnel
  workers。 Those who had disappearedwho had; seemingly; gone willingly
  up the   knotted   rope   to   hide   themselves   in the   valleykept   on   with   their
  work。 If they told their fellows why and where they had gone; the others

  gave no sign。 The evil spirits of the tunnel had been exorcised; and there
  was now peace; save for the blasts that were set off every so often。
  Tom     tried  combination      after  combination;     testing   them   inside   and
  outside the tunnel; always seeking for an explosive that would give a slow;
  rending effect instead of a quick blow; the power of which was soon lost。
  And at last he announced:
  〃I think I have it!〃
  〃Have you? Good!〃 cried Job Titus。
  〃Yes;〃 Tom went on; 〃I've got a mixture here that seems to give just
  the effect I want。 I tried it on some small pieces of rock; and now I want to
  test it on some large chunks。 Have you brought any down lately?〃
  〃Yes; we have some big slabs in there。〃
  Some large pieces of the hard rock; which had been brought down in a
  recent blast; were taken outside the tunnel; and in them one afternoon Tom
  placed; in holes drilled to receive it; some of his new explosive。 The rocks
  were set some distance away from the tunnel camp; and Tom attached the
  electric wires that were to detonate the charge
  〃Well;    I  guess   we're   ready;〃   announced     the   young    inventor;   as  he
  looked about him。
  The tunnel workers had been allowed to go for the day; and in a log
  shack; where they would be safe from flying pieces of rock; were Tom; Mr。
  Damon and the two Titus brothers。
  Tom held the electric switch in his hand; and was about to press it。
  〃This    explosive    works     differently   from    any   other;〃   he  explained。
  〃When the charge is fired there is not instantly a detonation and a bursting。
  The powder burns slowly and generates an immense amount of gas。 It is
  this gas; accumulating in the cracks and crevices of the rock; that I hope
  will burst and disintegrate it。 Of course; an explosion eventually follows;
  as you will see。 Here she goes!〃
  Tom   pressed   the   switch   and;   as   he   did   so;   there   was   a   cry   of   alarm
  from Mr。 Damon。
  〃Bless my safety match; Tom!〃 cried the old man。 〃Look! Koku!〃
  For;  as   the   charge   was   fired;   the giant   emerged   from  the   woods   and
  calmly   took     a  seat  on   the  rock   that  was   about   to  be  broken    up   into

  CHAPTER XXII
  The Fight
  〃Get off there; Koku!〃
  〃Stand up!〃
  〃Run!〃
  〃Get out uf the way! That's going up!〃
  Thus cried Tom and his friends to the big; good…natured; but somewhat
  stupid; giant who had sat down in the dangerous spot。 Koku looked toward
  the hut; in front of which the young inventor and the others stood; waving
  their hands to him and shouting。
  〃Get   up!   Get   up!〃   cried   Tom;   frantically。   The   powder   is   going   off;
  Koku!〃
  〃Can't you stop it?〃 asked Job Titus。
  〃No!〃   answered   Tom。   〃The   electric   current   has   already   ignited   the
  charge。 Only that it's slow…burning it would have been fired long ago。 Get
  up; Koku!〃
  But   the   giant  did   not  seem   to  understand。    He   waved    his  hand   in
  friendly greeting to Tom and the others; who dared not approach closer to
  warn him; for the explosion would occur any second now。
  Then Mr。 Damon had an inspiration。
  〃Call   him  to   come   to   you;  Tom!〃   shouted   the   odd   man。   〃He   always
  comes to you in a hurry; you know。 Call him!〃
  Tom acted on the suggestion at once。
  〃Here; Koku!〃 he cried。 〃Come here; I want you! Kelos!〃
  This   last   was   a   word   in   the   giant's   own   language;   meaning   〃hurry。〃
  And Koku knew when Tom used that word that there was need of haste。
  So; though he had sat down; evidently to take his ease after a long tramp
  through the woods; Koku sprang up to obey his master's bidding。
  And; as he did so; something happened。 The first spark from the fuse;
  ignited    by   the  electric  current;  had  reached    the  slow…burning     powder。
  There was a crackle of flame; and a dull rumble。 Koku sprang up from the
  122
  … Page 123…
  TOM SWIFT AND HIS BIG TUNNEL
  big stone as though shot。 What he saw and heard must have alarmed him;
  for he gave a mighty jump and started to run; at the same time shouting:
  〃Me come; Master!〃
  〃You'd better!〃 cried the young inventor。
  Koku got away only just in time; for when he was half way between
  the group of his friends and the big rock; the utmost force of the explosion
  was   felt。   It   was   not   so   very   loud;   but   the   power   of   it   made   the   earth
  tremble。
  The rock seemed to heave itself into the air; and when it settled back it
  was seen to be broken up   into many  pieces。 Koku looked   back over   his
  shoulder and gave another tremendous leap; which carried him out of the
  way of the flying fragments; some of which rattled on the roof of the log
  hut。
  〃There!〃 cried Tom。 〃I guess something happened that time! The rock
  is broken up finer than any like it we tried to shatter before。 I think I've got
  the mixture just right!〃
  〃Bless   my   handkerchief!〃   cried   Mr。   Damon。   〃Think   of   what   might
  have happened to Koku if he had been sitting there。〃
  〃Well;〃     said   Tom;    〃he  might    not   have   been    killed;  for   he  would
  probably have been tossed well out of the way at the first slow explosion;
  but   afterwardwell;   he   might   have   been   pretty   well   shaken   up。   He   got
  away just in time。〃
