six o'clock
The next day I was on camp guard . The weather was intensely cold . A bitter wind from the north swept the Maryland hills ; snow and rain and sleet fell , all together . For two hours , alternating with four hours ' relief , I paced my beat back and forth ; at six o'clock , when I was finally relieved , I was wet to the skin . When I reached my quarters , I went to bed at once and fell into a half sleep . Some time in the forenoon I found Dr. Khayme bending over me , with his hand on my temples . `` You have had too much of it , '' said he .
