three o'clock
There was no one to ask and none to object when they scrambled over the heaps of stone and plaster and wood , and tried the doors of the great ovens . Sure enough , there they found , well cooked and safe , a supply of bread and meat and sweets . Warren and Jack were broken-hearted at the absence of the slightest clue to Elinor , but they made a manly effort and managed to eat a good and nourishing meal , because they knew that they must keep up every bit of strength they had . At three o'clock by agreement they all met at the Professor 's house . Not one had secured a single clue . They had searched every empty and ruined building and had asked every person that they had seen . No one had been able to tell them anything that sounded at all helpful .
