Zack and Zeb proved to be model witnesses under Warriner's skilful tutelage. It was positively determined that no stranger had been near the library terrace between eleven and two o'clock on the day in question.
"Or anybody else?" asked Warriner.
"Miss Eunice she done come by thar; walkin' up fum de gyarding," answered Zeb.
"What time was that?"
"Ah reckon 'bout one o'clock, sah."
"How do you know? Do you carry a watch?"
"Nossah, but de oberseer's bell for de fiel' hands just done rung," asserted the witness with conviction.
"Where did Miss Trevor go?"
"I doan know, sah. I speck she went plum into de manshun house—roun' de cornah, sah."
Zack could add nothing more to this statement, and Zeb, when called in his turn, merely produced corroborative testimony.
