7:30
I had ignominiously to call upon Sandy to finish my speech . I realize that the best-equipped feminine mind in the world ca n't cope with the peculiar class of questions that originate in a thirteen-year boy 's brain . As a result of their seafaring interest , the doctor conceived the idea of inviting seven of the oldest and most alert lads to spend the day with him in New York and see with their own eyes an oceanliner . They rose at five yesterday morning , caught the 7:30 train , and had the most wonderful adventure that has happened in all their seven lives . They visited one of the big liners -LRB- Sandy knows the Scotch engineer -RRB- , and were conducted from the bottom of the hold to the top of the crow 's - nest , and then had luncheon on board . And after luncheon they visited the aquarium and the top of the Singer Building , and took the subway uptown to spend an hour with the birds of America in their habitats . Sandy with great difficulty pried them away from the Natural History Museum in time to catch the 6:15 train .
