Kaskaskia, 8th Oct: 1830.
Inclosed, you have, agreeably to your request, an estimate of the probable expense attending the emigrating Shawnees & Senecas from the State of Ohio, and the Miamies from Indiana, for the year 1831. If the information I lately recd [received] by the last party of Emigrating Senecas, is correct, the number stated in the Estimate will not fall short.
The calculation is made from the supposition that, as usual, they will remain few days to rest and by detention for crossing the Mississippi and from thence to the Kansas River, at $7:50 for each person, supposing one horse for each person.
The merchandise to be given is uncertain; it depends entirely upon the season in which they move:--Although there is no obligation to clothe them; yet it is impossible to refuse clothing to many women and children, suffering in cold weather.
Nothing is said about lost horses in their travels; but the past has proven that, in their journey when emigrating, number of horses have been stolen by our citizens, and more especially when they are crossing the Mississippi, our bad men steal them, and many others hide them in order to get a reward for bringing back what they have unlawfully taken. When their horses are stolen, and no hopes of getting them, then the Indians demand other horses in lieu of those stolen from them, and, say if our white brethren had not compelled us to move from our native land, our horses would not have been stolen, and we cannot travel with our wives and small children without horses.
The emigration of the Delawares in 1820, '21, & '22 [1821 & 1822] and that the Shawnees in '27,  has sufficiently proved that they cannot move without losing horses.
With respect & consideration,
Your obt. Servt. [Obedient Servant]
