About half way to Angolalah we crossed two or three of the earlier tributaries of the Barissa, which is a small river that collects the waters falling to the west of Tchakkah, and conducts them to the Abi or Nile of Bruce. All streams to the east of Tchakkah descend precipitously to join the Hawash. The Barissa derives its name from having been, previous to the reign of the present Negoos, the “boundary” between the Gallas and the Christian inhabitants of Shoa. It passes to the west of Debra Berhan, flowing towards the north, and joins the Jumma in the district of Marabetee. The Jumma also receives the Tcherkos river, or Lomee wans, which is now the western boundary of the kingdom of Shoa, the district intervening between it and the Barissa, a distance of about sixteen miles, having been annexed to his dominions within the last few years by Sahale Selassee. The Jumma, after receiving the Barissa, and other streams, of the kingdoms of Amhara and of Shoa, joins the Abi near where that river, after flowing to the south from Lake Dembea, turns suddenly to the west, and forms the southern border of the province of Gojam. We arrived at Angolahlah before noon, and Walderheros took me to the house of a friend of his, named Karissa. The weather, although only the latter end of June, was dreadfully cold, and being very tired and ill, I preferred rolling myself immediately up in my bed-clothes, consisting of two Abyssinian tobes, which my servant had carried with him in a skin-bag, rather than sit up to eat of some hard parched corn which was set before me by one of the women of the house.
