Next day they came to the boundary of the Great Park. It is the extreme north-eastern limit of Sidonia at this point there is erected a triumphal arch a hundred feet in height. On one side are the words "Welcome to Sidonia." On the other aide is written "Sidonia welcomes the river Sidon." Before it reaches this point the Sidon does a vast amount of irrigation work; it was feared that there would be no river left. Instead of that it has been found that irrigation increases the river flow.
Further north is the sweetwater sea but our party had spent three weeks in going from one part of the city to another and now they wanted to go home. They started back at thirteen o'clock by a local train to the north of Central Avenue; there they got the sixteen o'clock express that would land them at the Equatorial Hostel at twenty-one o'clock.
Thomas Frankston went to the reading room; Harry Hern and his beloved Emma might have been found sitting very near each other in a little conversational compartment; the five hours would not prove wearisome to them. Charles Frankston and Helen Vance were left to amuse each other.
"Well Helen we shall be home again in five hours; we cannot say that our pleasures will then be over but this delightful time will be a memory."
"For me a most pleasant one, Charley; kind friends, delightful weather, and a constant succession of experiences all new and changeful."
"I, too, Helen, look back on this as the very most enjoyable time of my life; and after all the time spent in your company is the enjoyment. If you had remained at home all would have been spoiled."
"There was never any serious danger of that. Emma could scarcely have gone so well if I had not been at liberty, and I will confess that I wished all the time to join the party."
"You did?" said Charley. "Then possibly what animates me has perhaps some influence upon you. Oh, Helen, how often a question has trembled on my tongue, and I have not put it because you appeared so practical and friendly, so like a sister. I have feared to ask lest the pleasant times we spend together should cease. I have feared again because there seemed to me some selfishness in asking you to devote your life to mine. I ask it now; can you love me? May we sweeten the cup of life for each other? Barry and Emma have set us the example, shall we follow them?"
Helen Vance again looked as she did when first she met Charley on Mars. As for the strange vibration in her voice that had never ceased. That far away look, that deep dumb something in the eye, what was it? Charley could never see it without a quiver; there was some meaning for him in it. "I would like to ask you a question or two, Charley, about your earth life. Mine has been finished for three earth years, yours is not yet over. I have heard you say that you have a wife and children there; I left a husband and three sons in Melbourne."
