When a transfer of pupils from one district to another is sought and the trustees of the latter district unreasonably or capriciously withhold their consent, the county board of education of the county in which the districts are located shall have the right, after hearing, to make the transfer, but only on condition that each pupil so transferred pay semiannually, in advance, if financially able to do so in the opinion of the board of trustees, as tuition, an amount not less than the per capita expenditure from the special tax for operating the school to which the pupil is to be transferred, together with all other charges paid by patrons of such district for any special course or courses.
