eight o'clock
`` Four are sometimes better than two , and in an adventure , such as this promises to be , four are always better than two . I say , let them come with us , by all means . '' And so it was decided . A meeting-place was arranged for eight o'clock that night , and , with this parting injunction , the officers left : `` Say nothing to anyone . Do not talk , even between yourselves , and , if you can , buy a revolver apiece , '' for the purchase of which the lieutenant tendered Hal a bill . It was a long afternoon for Hal and Chester , and they waited impatiently for the time when they were to meet the two young men who were to be their companions on the journey . After several futile attempts the lads finally gave up their attempt to buy revolvers , as it caused too many questions , and , in spite of their eagerness to get away , it was with no little anxiety that they made their way to the rendezvous that night .
