The Inquirer and Commercial News
, Perth gave an account of the voyage when the ship arrived at Fremantle.......
The convict ship Norwood Captain Frank Bristow, anchored in Gage's Roads at 6.30 pjn. on Saturday, 13th; Dr. Saunders, Staff Surgeon, R.N., Surgeon Superintendent, and Mr. Irwin, Religious Instructor; having on board a guard of 30 pensioners, 18 women and 30 children, 4 war- ders. with their families, and 253 convicts.
The ship was inspected on the 14th, and the prisoners all landed on that afternoon. No set of such men could have conducted themselves with greater subordination and good order than these did on the voyage out, and they were all landed in good health. Only one death occurred among the convicts, and no others. There have been four births on board.
The Norwood was here with convicts in 1862, under the superintendence of Dr. Watson, R. N., and she belongs to Messrs. J. H. Juscombe, of London.
Strong S.W. gales were encountered in the Channel, after leaving Portland on the 18th of April, with head winds as far as the Canaries. From thence fair average weather, with good trades. The Norwood had moderate winds in running down her easting, which she did between 39 and 40deg. S., until the 12th when a very heavy N.W. gale was encountered, which moderated early on the 13th, when she made Rottnest about noon.
Dr. Saunders has had charge of convicts for the first time, and the voyage has been most favourable with respect to the order, discipline, and cleanliness of the ship
