to the Katanga mining area, from Northern Rhodesia, and vice versa. In this con- nection I am to refer to your letter of the 23rd of December* and previous correspond- ence, and am to observe that it appears to Lord Crewe that a solution can best be found by means of discussion on the spot between the local authorities. The enclosure to your letter of the 16th of Septembert shows that the representative of the Katanga Committee in Africa was instructed to communicate with the North-Eastern Rhodesia authorities, but Lord Crewe has heard nothing further on the subject.

4. If Sir E. Grey concurs, Lord Crewe would propose to suggest to the British South Africa Company to endeavour to arrange a local conference, at which North- Eastern Rhodesia, the Katanga Administration, and the Union Minière would all be represented, with a view to full discussion of the whole question. Sir E. Grey will no doubt consider whether it is advisable or necessary first to approach the Belgian Government in the matter.

5. I am to add that the Katanga railway question is a subsidiary one, and the discussion in London which has been suggested, if it can be arranged, could prob- ably proceed without interfering with the proposed local conference.

2.

I also forward a small collection* of tsetse flies which have been obtained by Dr. Hopkinson during the last two months.

SIR,

I have, &c.,

I HAVE the honour to inform you that, with reference to tsetse flies, they have been noticed in Bathurst during and after the rains, but not in the dry season. They have been seen in Government House Compound under the trees, but not in any number.

I have also seen the fly at Oyster Creek Bridge occasionally.

SIR,

COLONIAL OFFICE to FOREIGN OFFICE.

Downing Street, 22 April, 1910. I AM directed by the Earl of Crewe to acknowledge the receipt of your letter of the 12th instant enclosing copies of correspondence with Mr. Beak (His Majesty's Vice-Consul at Katanga) and with His Majesty's Minister at Brussels regarding the measures taken and proposed by the local administration for prevent- ing the spread of sleeping sickness in the Katanga District.

Lord Crewe presumes that the position of affairs disclosed in the correspondence would not affect the suggestion contained in the letter from this Department of the 14th instant.§

I am to take this opportunity of forwarding, for Sir E. Grey's information, a copy of a despatch from the High Commissioner for South Africa enclosing a copy of a despatch from the Acting Administrator of North-Western Rhodesia and a copy of a report on sleeping sickness by Dr. May, Principal Medical Officer for Northern Rhodesia.

MY LORD,

Government House, Bathurst, Gambia, 6th April, 1910.

I HAVE the honour to acknowledge the receipt of your Lordship's despatch, No. 69, of the 1st June last, and in reply to it I beg to forward a short report by the Acting Senior Medical Officer dealing with the question of the presence of tsetse fly in St. Mary's Island and a fuller report, accompanied by a map.** by the Protectorate Medical Officer, Dr. Hopkinson, in which are indicated the localities where the tsetse fly is to be found in the Protectorate of the Gambia.

SIR,

Bathurst, April 8, 1910.

I HAVE the honour to return the map filled up to the best of my ability. I have marked on it the places where I have obtained specimens of tsetse flies this year and the districts where, from my experience of seven years, I know these flies to be plentiful. I must add, however, they are to be found practically throughout the Protectorate-especially numerous during the rains-except in some parts along the northern boundary and in the Upper River, where though present, they are more local. At present, unfortunately, I cannot distinguish the different species, but from their habits know at least two, one of which is never found away from water, the other in the bamboo growth on ironstone country, which occupies a large proportion of the country. The bite of the latter is the most painful both to man and horse. The hardest biting fly here, however, is the large Mangrove fly (a Tabanus), which also troubles horses a great deal. These animals, however, fear and feel the bite of a small spot-winged fly more than that of any other species. This is, I believe, Chrysops dimidiatus. I have never known a tsetse fly to bite at night, but then, fortunately, I have rarely been in the bush at such a time.

The places where one is most likely to get bitten are in Nuimi and Kiang, or when travelling by river from about Elephant Island to McCarthy.

Sleeping sickness is fortunately rare in the Gambia; I have only heard of two cases in the last twelve months-one from Willimissa, in Kiang; the other from Kudang, in Niamina. Native tradition seems to point to the fact that much more common in former days.

was

On the map I have also marked (blue) the parts where horses do well, though even here the rainy reason kills off a good many. The districts thus marked are practically those where tsetses are least troublesome.

With the map is a small collection of tsetse and other flies collected during the last two months. The unmounted ones all come from the McCarthy Island

Province.

In conclusion, I have the honour to request that the expert to whom the flies are sent be requested to send us some named specimens of the flies particularly required to help us in future identification.

For this purpose I find the uncoloured figures in the books we have useless.

I have, &c.,

The Acting Senior Medical Officer.

EMILIUS HOPKINSON,

Protectorate Medical Officer.
