Gambaran persempadanan Kajang dan daerah sekitarnya, berdasarkan peta tahun 1904.

Sempadan: Sungai Sabak Dua, Bukit Belachan, Bukit Rang(Arang?), dan Genting Peras: “The Dusun Tua (or “Old Orchard”) at the Hot Springs was, it need hardly be said, originally planted by Sakais, but was appropriated by one Si Timah, a daughter of Toh Langat, who sold it to the “Towkay Bahru” of Ulu Langat. Toh Langat's boundaries are said to have been Sungei Sabak Dua, Bukit Blachan, Bukit Rang and Ginting Peras.” (1897: The Selangor Journal: Jottings Past and Present, Volume 5, hlm.305-306).

Sempadan: Sungai Sabak Dua, Subang Hilang: “The boundaries of Inche Lili's domain were the district of Ulu Langat from Sungei Sabak Dua upstream following the Dato' Langat's boundary and downstream following the boundary of Dato' Ali as far as Subang Hilang.” (1897: The Selangor Journal: Jottings Past and Present, Volume 5, hlm.306-307).

Dalam perjalanan ke Subang Hilang, perlu lalui Amparan Tenang (tebing kanan Sungai Langat, mudik dari Kuala Labu), sekitar Simpang Ampat:-

“Kajang
17th Sept: 1884.

Sir.
I have the honour to report that on my way to Subang Ilang on Thursday last I spent the night at a place called Amparan Tenang on the right bank of the R. Langat above K. Labu.
2. The campong is owned by a man named Mahomed Deriss who is very anxious to be made a sort of head over the Sakeis living between Subang Ilang & Sempang Ampat. He has great influence with these people who on their part entertain a great liking for him and as I think such an arrangement would be beneficial to that part of my District I beg respectfully to bring this to your notice for approval.
3. Mahomed Deriss is the son of Datoh Allee, Penghulu of Teluk Datto, in the Langat District.

I have the honour to be
Sir
Your most obedient servant
George C. Bellamy
Ag: C. of ?”
