four o'clock
Quite a crowd had gathered , some in sleighs and some on foot , and the surface of the lake was covered with skaters . When the hockey game started the crowd watched every move with interest . It was a `` hot '' game , according to Bert , and when a clever play was made he applauded as loudly as the rest . When the game was at an end he was sorry to discover that it was after four o'clock . `` We must get home , '' said he to Bob . `` I promised to be back by five . '' `` Oh , we 'll get back in no time , '' said Bob .
