(1) _Dubbo._—A property in Bauchi, Northern Nigeria, consisting of 632 acres. This property is under the charge of two engineers. (2) _Rafinsiroma._—This is a small rich property of 33 acres adjoining Dubbo to the south, and capable of immediately producing tin by ground sluicing and calabashing. (3) _Bengalili._—A property of about 320 acres on the river Bukeru, situated about one mile to the north of Dubbo, and capable of producing tin by handworking at once. (4) _Bengalili North._—This is an area of about 120 acres adjoining and to the north of the Bengalili property, also capable of producing tin by sluicing and calabashing. The river runs through this property. (5) _Polchi._—A property of 84 acres adjoining South Juga, and situated on the main road from Toro to Bauchi. The property is now being worked and is producing tin. (6) _Boidun._—This property is situated on the road from Dubbo to Bri, and is about one mile west of Dubbo. It extends for a distance of about a mile along the river. (7) _Bilidi River._—Three square miles, or 1,920 acres. Good tin was found on this property, besides an appreciable amount of gold in the wash. (8) _Kurdum._—Five square miles, or 3,200 acres. On the tests made the overburden went 3 lbs. of tin for 7 feet, and the bottom wash went 60 lbs. of tin for 1 foot. (9) _Kwall Falls._—The first application was made on behalf of this company for this power, which would be of great value, as it gives 2,000 horse-power in the dry season, and commands several properties. The _Dubbo_ property is situated near the village of Dubbo, on the Dubbo River, and west of the Soli Hills. It is sometimes described as Topaz Valley, so named on account of the large quantity of topaz found in the wash. It is situated about six miles north of Juga. The Lireui natives have done a lot of work on this property, sinking shafts in some cases a hundred yards back from the Dubbo River. These shafts run from 8 to 10 feet in depth, proving that the bottom wash must have been very rich for, as a rule, the Lireuis only mined shallow ground where the wash is easily got. Mr. Lush said that he had not seen similar work in any other part of the tin district.
