22245How many people did the train hold?
22245I asked, sir, if that pocketbook was your property?
22245I beg pardon, sir,said he with deference,"but does that pocketbook belong to you?"
22245I wonder what they would have said if somebody had told them then that sometime people would be going from Boston to New York in five hours?
22245If Dad does n''t want us to go there that''s enough, is n''t it?

22245It is a pretty fine car, is n''t it?
22245It was a fortunate thing they did, was n''t it?
22245It was tough on Fulton and his friends, though, was n''t it?
22245It was, was n''t it?
22245It would be a jolly subject for a debate, would n''t it?
22245It would be a terrible humiliation if I should discover that I could not do it, would n''t it?
22245It''s a great game-- living-- isn''t it, Dad?

22245Nobody else is responsible for you?
22245Not all the thieves you arrest take you to a theater party afterward, do they, Officer?
22245Nothing?
22245Oh, he will be here directly, will he? 22245 Opposed to it?"
22245Our boys have done well, have n''t they, Ackerman? 22245 Pretty tough, was n''t it?"
22245Railroad officials would have some job to list passengers now, would n''t they?

22245So far as I can see we shall have to leave the matter a draw, sha n''t we, Tolman?
22245So the pocketbook was at your house over night?
22245So the railroad men were converted, were they?
22245So you are a skater, are you, Tolman?
22245So you like my moving picture, do you, Steve?
22245So your father did not know you had the car out the other day?
22245Some city, is n''t it?
22245Some show, eh, son?
22245Steamboats?
22245Such as?
22245Suppose I knew nothing about it, where would we be? 22245 That is a squarer deal, is n''t it?"
22245That plan sounds rather nice, does n''t it, Jane?
22245The State stuck to its bargain, then,murmured Steve,"and left Livingston the rights awarded him?"
22245The inspectors or somebody else would have put an end to such a crazy scheme jolly quick if it had been in our day, would n''t they?
22245Think you would have preferred to cross the continent by wagon rather than by train?
22245Three?
22245To- morrow?
22245Trap me?
22245Was it Watt who invented the locomotive, too?
22245Was it really as bad as that before the railroads were built?
22245Was n''t he the one who tried sails on a railroad train?
22245Was the trip a success?
22245We have got that match to play off, and now that the electric cars are held up by the strike how are we to get to Torrington? 22245 Well, my boy, what have you to say for yourself?"
22245Well, son, have you enjoyed your holiday?
22245Well, son,said he, as they took their places in the large dining room,"what is the prospect for to- day?
22245Well, the railroads were built just the same, were n''t they?
22245Well, we caught it, did n''t we, Dick? 22245 Well, what is up for to- day, boys?"
22245Well, why do n''t you say something?
22245Well?
22245Were any more railroads like the Quincy road built in America?
22245Were there other races like that?
22245What are we going to do, Dad?
22245What are we in the world for if not to do one another a good turn when we can?
22245What are you planning to do with Dick, Stephen?
22245What are you thinking of, son?
22245What became of the clipper ships?
22245What business is that of yours?
22245What did he do then?
22245What did you do with it?
22245What do you think yourself?
22245What engines did follow?
22245What happened?
22245What is it?
22245What is the matter with the car?
22245What is there to say?
22245What was the first American steamship to cross the Atlantic, Ackerman?
22245What would they have said to crossing the water by aeroplane or bobbing up in a foreign port in a submarine?
22245What''s hindering you?
22245What''s the good of being such a boob? 22245 What''s the trouble with your machine?"
22245What''s wrong, Ackerman?
22245What''s wrong, Henry?
22245When did England adopt railroads in place of stagecoaches, Dad?
22245When was the first American railroad built?
22245Where are you going?
22245Where are you staying?
22245Where is he?
22245Where is that child?
22245Where was New England all this time?
22245Who did finally invent the railroad?
22245Who do you live with?
22245Who wants me?
22245Who''s going to be the wiser if you do take the car? 22245 Who''s this?
22245Why do n''t we go, too?
22245Why should n''t you make me proud of you?
22245Why, they could have marched it in less time than that, could n''t they?
22245Why?
22245You are a detective?
22245You are sure no one took the things out while you were asleep last night?
22245You checked your coat and left it there?
22245You do n''t mean that you left it in your ulster pocket and let them hang it out there on the rack?
22245You knew before we went skating then?
22245You know what I did?
22245You liked Mr. Ackerman also, did n''t you, son? 22245 You mean somebody thinks my son took the pocketbook?"
22245You mean that even now it is n''t too late?
22245You recall how even the more civilized and better educated English and French opposed the first railroads? 22245 You think there are handsomer boats in the room than these, do you?"
22245You''re going back to school, are n''t you, youngster?
22245You-- you-- won''t tell my father about my taking the car, will you?
22245_ I_ tell him?
22245A moment later a cheery voice which Steve at once recognized to be that of the steamboat man came over the wire:"Well, sonny?"
22245Ackerman?"
22245Ackerman?"
22245Ackerman?"
22245Alas, was he never to be free of the nagging mortification that had followed that single act?
22245And if afterward, who took them?
22245And where was the workmen''s food to come from if they were plunged into a wilderness beyond the reach of civilization?
22245Anyhow, you have run it before, have n''t you?
22245Are you feeling fit for more adventures?"
22245Are you satisfied and ready to go to bed and to sleep now?"
22245Besides, I sha n''t do it again, so what is the use of jawing about it?"
22245But was the folly so terrible?
22245But what, he argued, could he do?
22245Can you ask for anything more primitive than that?"
22245Did n''t the Indians attack the workmen?
22245Did not iron always sink?
22245Did not the old adage say that"experience is the best teacher"?
22245Do you remember?"
22245Do you think if my father had a car and it was standing idle in the garage when a bunch of kids needed it to go to a school game I would hesitate?
22245Doris persisted,"and who did invent our steam engine?"
22245Eh, son?"
22245Even suppose the boys did remember to send back help( they probably wouldn''t-- but suppose they did) how was he to pay a machinist?
22245Every moment he expected that his father or Havens would wheel on him and ask accusingly:"When was it you carried all those boys to Torrington?"
22245Fainting away?"
22245For a moment he could not speak; then when he had caught his breath he exclaimed excitedly:"How can I get some gasoline?"
22245Had not the workman who had replenished it Wednesday said quite plainly that there was only enough gas in it to get him home to Coventry?
22245He has been compelled to bone down like a beaver to go ahead with his class; but he has succeeded, have n''t you, sonny?"
22245He was safely out of the entanglement and was it not just as well to accept his escape with gratitude and let sleeping dogs lie?
22245How about yours, Steve?"
22245How could I have?"
22245How could they?"
22245How did you sleep?"
22245How is that?"
22245How was America to know anything different?
22245However, if he wants to have a second glimpse of our boats now we''ll let him, wo n''t we, Dick?"
22245If he began to ask questions might not the stranger assume the same privilege and wheel upon him with some embarrassing inquiry?
22245If he had known the thing was valuable, do you suppose he would have left it in his ulster pocket and checked the coat in a public place like this?"
22245Is n''t that so, Havens?"
22245Is that a bargain, youngster?"
22245It seems odd, does n''t it?"
22245It tells its own story, does n''t it?"
22245Just because I happen to be a superintendent do you think me a volume of railroad history, young woman?
22245Moreover, to build a railroad of such length would take a lifetime and where was the money coming from?
22245Neither Stephen nor I cherish the least ill- will about the affair; do we, son?"
22245O''Malley?"
22245Our commerce reaches out to every corner of the earth and why should we rely on other countries to transport our goods?"
22245Presently his mother called from the tonneau:"Is n''t that the Taylors''car, Henry, coming toward us?
22245So you want to hear more about it, do you?"
22245Some day he will be driving it alone, wo n''t you, son?"
22245Such contingencies were of course to be deplored but as they could not be helped, why let them ruin the entire holiday?
22245Suppose we divide up the responsibility and foist half of it on Stephen?
22245The boy knew he had done nothing wrong; but would he be able to convince the detective of the truth of his story?
22245Then the newcomer came to a stop and he heard a pleasant voice:"What''s the matter, sonny?"
22245Then turning toward his wife, he added in bantering fashion:"Are n''t you getting a little frivolous, my dear?
22245There is no filling him up; is there, boy?"
22245Vanderbilt?"
22245Was it always to lurk in the background and make him ashamed to confront the world squarely?
22245Was it not like the railroad trains used in England?
22245Was there ever writer more tantalizing?"
22245We should very much enjoy having you, should n''t we, Stephen?"
22245Were the things taken out before the bill book fell into your son''s hands or afterward?
22245What business was it of his, anyway, and why was he so solicitous as to where he went?
22245What did they do?"
22245What do you say?"
22245What do you say?"
22245What if the stranger should ask to see it?
22245What if there had been valuable papers in it, money-- a great deal of money-- and now through his carelessness it had all disappeared?
22245What is the use of spoiling a fine morning like this talking business?"
22245What is to become of him now?
22245What is your theory?"
22245What on earth has happened to the thing, Havens?
22245What reason had he to suppose a mishap would befall him when they were not by?
22245What should he do with it?
22245What was he to do?
22245What would be the use of telling?
22245What would his father think of him if he knew what a mean- spirited coward he was?
22245Where did we break off our story?
22245Who could blame him for not wanting to confess his misdemeanors before an audience?
22245Who had the chance?
22245Who knows?
22245Who was this mysterious mechanic and why should he assume with such certainty that Coventry was the abiding place of the car?
22245Who would not have liked, for example, to set out with Mr. Pickwick for the Christmas holidays at Dingley Dell?
22245Whom shall I ask for at the hotel?"
22245Why do n''t you plan to do that too, Ackerman?
22245Why not let the matter rest there?
22245Why not speak out now and clear up the wretched deception he had practiced, and start afresh with a clean conscience?
22245Why not?
22245Why not?"
22245Why was n''t it better anyway to wait until he and his father were quiet and alone?
22245Will not the world be the better for all these things?
22245Will that be agreeable to you?"
22245Would it not be much wiser to wait?
22245Yet how could he have stopped at the Coventry garage even had he thought of it?
22245You are going right back, are n''t you?"
22245he protested good- humoredly,"what do you think I am?
