This advertisement by Whitman and Searl of Lawrence, Kansas Territory, states that they propose to open an Emigrant's Intelligence Office to "meet the urgent demands by emigrants, for accurate and reliable information in regard to the different sections of the Territory." Apparently, they had created a map of Kansas, which made them qualified for this task. They also offer their services as general land agents, and write that they "are also prepared to lay out town sites and to survey farm claims," to "negotiate the sale and transfer of town property," and to "investigate the validity of titles."
