By nightfall Bob had saturated his brain with legal lore bearing on every feature of the laws governing the acquisition of lands in the public domain, and was satisfied that the hazy plan which he had outlined was not only within the law, but really did have some vague elements of feasibility. The beauty of Bob's plan, however--the part that appealed to the sporting instinct in his ultra-sporty soul--lay in the fact that it would cost him only fifteen hundred dollars to try! Twelve hundred and seventy-five in preliminary payments, filing fees and notary's fees, and the balance in hotel bills, traveling expenses, etc.; but as an offset to his comparatively brilliant prospects of going hungry and ragged there was the dim, long chance that he _might_ win millions, provided his venture should be attended with a fair percentage of supernatural luck. That was all Bob McGraw had to cheer him on to victory--a million-to-one chance; yet, such was his peculiar mental make-up, the terrific odds only proved an added attraction. CHAPTER X Now; in order to insure even perfunctory understanding of the procedure under which Bob McGraw planned to acquire his lands, and to give an inkling of the difficulties confronting him, it is necessary that the reader take a five-minute course in land law. This is regrettable, for it is a dry subject, even in the matter of swamp and overflow lands, so we shall endeavor to make the course as brief as possible. Section sixteen and thirty-six in each township throughout the United States are commonly designated as “school lands,” for the reason that the Federal government has ceded them to the various states, to be sold by the states for the use and benefit of their public school funds. School lands are open to purchase by any citizen of the United States, and in the case of California school lands the statutory price is one dollar and twenty-five cents per acre. Now, frequently it happens that by reason of the inclusion of certain of these “school lands” in a Forest Reserve, a Reclamation District, an Indian Reservation, a National Park, a Government Military Reservation or an old Mexican grant (which latter condition obtains very frequently in California, where the titles to many huge grants still hold since the days of the Mexican occupation) they are lost to the state. In such cases, the Federal government reimburses the state suffering such loss of school lands, by extending to the state the privilege of selecting from the public lands within its borders an acreage corresponding to the acreage thus lost by reason of inclusion in a restricted area. The lands thus selected from the public domain in exchange for school lands lost to the state, having been taken in lieu, thereof, are known as “state lieu lands,” and the lands which were originally state school lands and which have been lost to the state by reason of their inclusion in some restricted area, are spoken of as the “basis” for the exchange.
