1. Exportation of arms etc. from United States

1. Air rifles.-Paper caps for toy cap pistols could hardly be considered within the prohibition of the President's proclamation of March 14, 1912, issued pursuant to the joint resolution of the same date, forbidding the exportation of arms and munitions of war to Mexico, whereas air rifles might well be regarded within the prohibition. The question, however, is one of fact, dependent upon the character of the articles sought to be imported. 29: 570.

2. Same. Whether certain air rifles are "arms or munitions of war" within the meaning of the joint resolution of Congress passed March 14, 1912, and the President's proclamation of the same date issued in pursuance thereof, is purely a question of fact which the Attorney General does not feel quali

1. Lease of mine for experimentations. The leasing of a mine in Pennsylvania by the United States, on a cash payment of $1,500, for experimentations in mine rescue work, constitutes a purchase of land within the meaning of section 3736, Revised Statutes, which provides that no land shall be purchased on account of the United States, except under a law authorizing such purchase. 28: 463.

2. Same.-The statement in the opinion of September 15, 1910 (28 Op. 413), that it would be a wise precaution to have the titles to tracts of land to be acquired for the abovenamed purpose submitted to the Attorney General for his opinion as to validity, regardless of whether section 355, Revised Statutes, be applicable or not, contains no intimation that when section 355 does not apply the opinion of the Attorney General is not necessary. 28: 463.

Where automobile manufacturers sell and deliver to a foreign buyer in the United States automobile trucks and the trucks are exported by the buyer, the sales thus made are taxable under section 600 of the war revenue act of October 3, 1917 (40 Stat. 316). 32: 567.

3. Transfer of motor vehicles by Secretary of War for improvement of highways. Section 5 of the sundry civil act of July 19, 1919, which relates to the disposal by the Secretary of War of motor-propelled vehicles and motor equipment, does not repeal section 7 of the act of February 28, 1919 (40 Stat. 1201), and hence the power of the Secretary of War remains in full force "in his discretion to transfer to the Secretary of Agriculture all available war material, equipment, and supplies not needed for the purposes of the War Department, but suitable for use in the improvement of highways * * * to be used on roads constructed in whole or in part by Federal aid." 32:45.
