  TOM SWIFT AND HIS BIG TUNNEL
  lummox ob a giant! He done knocked de breff outen me; so he did。〃
  〃You   come   back   from   that   stone   pile!〃   Tom   ordered。   〃I'm   going   to
  blow   it   up   in   a   minute;   and   if   you   get   too   near   you'll   have   the   breath
  knocked out of you worse than Koku did it。 Come back; I say!〃
  But   Eradicate   was   obstinate   and   kept   on。 Tom;  who   was   adjusting   a
  firing battery in the shack; laughed; and then in exasperation cried:
  〃Koku;   go   and   get   him   and   bring   him   back。   Carry   him   if   he   won't
  come any other way。 I don't want the dear old chump to get the fright of
  his life; and he sure will if he goes too close。 Bring him back!〃
  〃Koku bring; Master;〃 was the giant's answer。
  He    ran   toward    Eradicate;    who;    seeing    his  tormentor     approaching;
  redoubled his shuffling pace toward the stone pile。 But he was no match
  for   the   giant;   who;   ignoring     his  struggles;    picked    up  Eradicate;     and;
  flinging   him   over   his   shoulder   like   a   sack   of   meal;   brought   him   to   the
  shack。
  〃There him be; Master!〃 said the giant。
  〃So I see;〃 laughed Torn。 〃Now you stay here; Rad。〃
  〃No;   sah!    No;   sah;   Massa   Tom!   II'se   gwine   t'   git   a   rock   an'an'
  bash his   haiddat's what   I'se   gwine t'   do!〃 and   the   colored man   tried   to
  struggle to his feet。
  〃Look out now!〃 cried Tom; suddenly。 〃If things go right there won't
  be a rock left for you to 'bash' anybody's head with; Rad。 Look out!〃
  The three cowered inside the shack; which; though it was rudely made;
  was   built   of   beavy   logs   and   planks;   with   a   fronting   of   sod   and   bags   of
  sand。
  Tom turned a switch。 There was a loud report; and where the stone pile
  had been there was a big hole in the ground; while the air was filled with
  fragments of rock and dirt。 These came down in a shower on the roof of
  the shack; and Eradicate covered his ears with his trembling hands。
  〃Amam de world comin' to de end; Massa Tom?〃 he asked。 〃Am dat
  Gabriel's trump I done heah?〃
  〃No; you dear old goose!〃 laughed the young inventor。 〃That was just
  a charge of my new explosivea small charge; too。 But it seems to have
  done the work。〃

  TOM SWIFT AND HIS BIG TUNNEL
  He ran from the shack to the place where the rock pile had been; and
  picked up several small fragments。
  〃Busted all to pieces!〃 exulted Tom Swift。 〃Not a piece left as big as a
  hickory   nut。   That's   going   some!   I've   got   the   right   mixture   at   last。   If   an
  ounce did that; a  few hundred pounds ought   to knock that Andes   tunnel
  through the mountain in no time。 I'll telegraph to Mr。 Titus。〃
  Leaving Koku and Rad to collect the wires and firing apparatus; there
  being no danger now; as no explosive was left in the shack; Tom made his
  way back to the house。 His father met him。
  〃Well; Tom;〃 he asked; 〃another failure?〃
  〃No; Dad! Success! This time I turned the trick。 I seem to have gotten
  just the right mixture。 Look; these are some of the pieces left from the big
  rockone of the samples Mr。 Titus sent me。 It was all cracked up as small
  as this;〃 and he held out the fragments he had picked up in the field。
  Mr。 Swift regarded them for a few moments。
  〃That's better; Tom;〃 he said。 〃I didn't think you could get an explosive
  that would successfully shatter that hard rock; but you seem to have done
  it。 Have you the formula all worked out?〃
  〃All   worked   out;   Dad。   I   only   made   a   small   quantity;   but   the   same
  proportions will hold good for the larger amounts。 I'm going to start in and
  make it now。 And thenHo! for Peru!〃
  Tom     struck   an   attitude;  such   as   some    old  discoverer    might    have
  assumed; and then he hurried into the house to telephone a telegram to the
  Shop' ton office。 The message was to Mr。 Titus; and read:
  〃Explosive     success。    Start  making     it  at  once。   Ready    for  Peru   in
  month's time。〃
  〃Thirteen words;〃 repeated Tom; as the operator called them back to
  him。 〃I hope that doesn't mean bad luck。〃
  The   experiment   which   Tom   Swift   had   just   brought   to   a   successful
  conclusion   was   one   of   many   he   had   conducted;   extending   over   several
  wearying weeks。
  As soon as Tom had received the samples of the rock he had begun to
  experiment。 First he tried some of the explosive that was so successful in
  the giant cannon; As he had feared; it was not what was needed。 It cracked
  28

  TOM SWIFT AND HIS BIG TUNNEL
  the rock; but did not disintegrate it; and that was what was needed。 The
  hard rock must be broken up into fragments that could be easily handled。
  Merely to crack it necessitated further explosions; which would only serve
  to split it more and perhaps wedge it fast in the tunnel。
  So   Tom   tried   different   mixtures;   using   various   chemicals;   but   none
  seemed to be just right。 The trials were not without danger; either。 Once; in
  mixing some ingredients; there was an explosion that injured one man; and
  blew   Tom   some   distance   away。   Fortunately   for   him;   there   was   an   open
  window in the direction in which he was propelled; and he went through
  that; escaping with only some cuts and bruises。
  Another time there was a hang…fire; and the explosive burned instead
  of detonating; so that one of the shops caught; and there was no little work
  in subduing the flames。
  But Tom  would not   give   up;  and   finally;  after   many  trials;  he   hit   on
  what he felt to be the right mixture。 This he took out to the big lot; and
  having made a miniature tunnel with some of the sample rock; and having
  put some of the explosive in a hole bored in the big chunk Koku carried;
  Tom fired the charge。 The result we have seen; It was a success。
  A    day   after  receiving    Tom's     message     Mr。   Titus   came    on   and   a
  demonstration was given of the powerful explosive。
  〃Tom; that's great!〃 cried the tunnel contractor。 〃Our troubles are at an
  end now。〃
  But; had he known it; new ones were only just beginning。
  Tom at once began preparations for making the explosive on a large
  scale; as much of it would be needed in the Andes tunnel。 Then; having
  turned    the   manufacturing      end   of   it  over  to  his  men;    Tom    began    his
  preparations for going to Peru。
  Mr。 Damon was also getting ready; and it was arranged that he; with
  Tom and Mr。 Titus; should take a vessel from San Francisco; crossing the
  continent by train。 The supply of explosive would follow them by special
  freight。
  〃We   might   have   gone   by   Panama   except   for   the   slide   in   the   canal;〃
  Tom   said。   〃And   I   suppose   I   could   take   you   across   the   continent   in   my
  airship; Mr。 Titus; if you object to railroad travel。〃

  TOM SWIFT AND HIS BIG TUNNEL
  〃No; thank you; Tom。 If it's just the same to you; I'd rather stay on the
  ground;〃 the contractor said。 〃I'm more used to it。〃
  A day or so before the start for San Francisco was to be made; Tom;
  passing a store in Shopton; saw something in the window he thought Mary
  Nestor     would    like。  It  was   a  mahogany       work…box;     of  unique    design;
  beautifully decorated; and Tom purchased it。
  〃Shall I have it sent?〃 asked the clerk。
  〃No; thank you;〃 Tom answered。
  He knew the young lady who had waited on him; and; for reasons of
  his own; he did not want her to know that Mary was to get the box。
  Carrying   the   present   to   his   laboratory;   Tom   prepared   to   wrap   it   up
  suitably to send to Mary; with a note。 Just; however; as he was looking for
  a box suitable to contain the gift; he received a summons to the telephone。
  Mr。 Titus; in New York; wanted to speak to him。
  〃Here; Rad!〃 Tom called。 〃Just box this up for me; like a good fellow;
  and then take it to Miss Nestor at this address; will you?〃 and Tom handed
  his   man   the   addressed   letter   he   had   written   to   Mary。   〃Be   careful   of   it;〃
  Tom cautioned。
  〃Oh; I'll be careful; Massa Tom;〃 was the reply。 〃I'll shore be careful。〃
  And Eradicate wasall too careful。
