Here that the lieutenant wrote about them in 1859 Warren:

' Though geographical co-ordinates at Bonvillja are given is inexact, however its cards have revealed presence of the big internal, not having drain to ocean of the pool consisting of the Big Salty lake, the river of Ogden or Mary (nowadays Humboldt), lakes Mad, lake and the river Sever, and also have finished the version about the imaginary river Buenaventura and a number of others. On cards Bonvillja the length of the river Villamet is reduced till its valid sizes and its sources are approximately specified, and also the extent and a direction of a current of the rivers Sacramentos and San Joaquin is shown.

Its card of sources of the river Yellowstone still is best of primary sources on this area '.

It is necessary to tell, that Warren overestimated value of cards Bonvillja. It is impossible even to name its cards the first exact cards of the West for in 1836, one year prior to their occurrence, A.Gallatin has made a card of the Western America and has given it in the form of the appendix to the work ' the Collection of materials about American Indian tribes in territory of the United States '. But its card remained a little known whereas card Bonvillja has been widely advertised by the writer Washington Irving.
