The examination of this witness here closed.

The judge-advocate stated that there were no other witnesses in attendance, and there might be none for several days. Some of them were in active service in the field at this time, and others were at remote points, at which they had been telegraphed.

The court accordingly adjourned to 11 a.m. on Thursday next.
