that his mind was affected, I said, “Now, Sekwebu, we are going to Ma Robert.”  This struck a chord in his bosom, and he said, “Oh yes; where is she, and where is Robert?” and he seemed to recover.  The officers proposed to secure him by putting him in irons; but, being a gentleman in his own country, I objected, knowing that the insane often retain an impression of ill treatment, and I could not bear to have it said in Sekeletu’s country that I had chained one of his principal men as they had seen slaves treated.  I tried to get him on shore by day, but he refused.  In the evening a fresh accession of insanity occurred; he tried to spear one of the crew, then leaped overboard, and, though he could swim well, pulled himself down hand under hand by the chain cable.  We never found the body of poor Sekwebu.

At the Mauritius I was most hospitably received by Major General C. M. Hay, and he generously constrained me to remain with him till, by the influence of the good climate and quiet English comfort, I got rid of an enlarged spleen from African fever.  In November I came up the Red Sea; escaped the danger of shipwreck through the admirable management of Captain Powell, of the Peninsular and Oriental Steam Company’s ship “Candia”, and on the 12th of December was once more in dear old England.  The Company most liberally refunded my passage-money.  I have not mentioned half the favors bestowed, but I may just add that no one has cause for more abundant gratitude to his fellow-men and to his Maker than I have; and may God grant that the effect on my mind be such that I may be more humbly devoted to the service of the Author of all our mercies!
