Article 4.--Any one purposing to go the said route will intimate his intention to the Agent of either State, and apply for a passport, agreeably to a form to be laid down; having obtained which, he may proceed on his journey. The merchants coming from Umritsur, and other parts on the right bank of the river Sutlej, are to intimate their intentions to the agent of the Maharajah, at Hurrekee, or other appointed places, and obtain a passport through him; and merchants coming from Hindoostan, or other parts on the left bank of the river Sutlej, will intimate their intentions to the Honourable Company's Agent and obtain a passport through him. As foreigners, and Hindoostanees, and Sirdars of the protected Sikh States and elsewhere, are not in the habit of crossing the Sutlej without a passport from the Maharajah's officers, it is expected that such persons will hereafter also conform to the same rule, and not cross without the usual passports. Article 5.--A tariff shall be established exhibiting the rate of duties leviable on each description of merchandise, which, after having been approved by both Governments, is to be the standard by which the superintendents and collectors of customs are to be guided. Article 6.--Merchants are invited to adopt the new route with perfect confidence: no one shall be suffered to molest them or unnecessarily impede their progress, care being taken that they are only detained for the collection of the duties, in the manner stipulated, at the established stations.
