_May 5th, Sunday_.--Attended Mr. Moffat's church; the service is held in the Bechuana language. About 400 natives present. The singing is as well performed as it is in any English church at home. The Kaffirs, who are Bechuanas, have fine clear voices, and the women are well known to have sweet, musical voices. The service is well-conducted, and the natives as attentive as any white congregation in a civilised country. I first attended at this church in February 1868, when the Rev. Robert Moffat was living there, previous to his finally leaving for England. On 29th December, 1869, I was again there, detained for many weeks with a severe illness, and through the kind nursing of Mr. and Mrs. John Moffat, Mr. and Mrs. Levy, and other English residents, soon recovered. I remember well before leaving at that time they got up a little picnic party, to visit some ancient Bushmen caves, a few miles from the mission station towards the hills, taking a cart with provisions, the party riding, and a very enjoyable day we had. As we approached the hills the country became covered with bush and long grass, where I may safely say, several hundreds of baboons were busy seeking roots. The old men were very large, and to see the whole troop scuttle towards the hills with the babies on their mothers' backs, with their little arms clinging round their necks, was a pretty and novel sight. Arriving at the caves, we found a long sand cliff projecting many yards over the lower part, affording shelter for several hundred families, perfectly secure and a safe retreat--but its ancient inhabitants are passed away and forgotten. We procured some very beautiful specimens of the trap-door spider; the workmanship of the door and its hinge, and the lining of the passage down to their nest is something marvellous. So far as I have discovered, there are three kinds of this species, distinguished by their size. The largest is a black spider, the body nearly an inch in length; the opening, or passage, and the door to their nest is the size of our English florin; the hole to the nest is perpendicular for from a foot to two feet, when an open space is beyond. The coating of this opening and the under side of the door is of a greyish white, and as soft and smooth as satin, and when the door is shut it fits so exactly as to be quite watertight. The top of the door is made to represent the ground round about, to be undistinguishable by an enemy. The second size trap-door is the size of a shilling, and the third the size of a fourpenny-bit. But the spiders are of the same type; where one kind is found in a district the others are not, showing they occupy separate localities. I have frequently found the door open and thrown back, showing the spider is abroad hunting up game to supply his larder. On several occasions when finding these doors open I have watched the return of the spider, sitting down a few feet from the door, and waited sometimes nearly half an hour.
