All homestead entries which have been canceled or relinquished, or are invalid solely because of the erroneous allowance of such entries after the withdrawal of lands for national-forest purposes, may be reinstated or allowed to remain intact, but in the case of entries canceled prior to March 3, 1911, applications for reinstatement must have been filed in the proper local land office prior to July 1, 1912.
