Toward the close of his reign, and very soon after the departure of Lord Amherst, Kiaking was brought face to face with a very serious conspiracy, or what he thought to be such, among the princes of the Marichu imperial family. By an ordinance passed by Chuntche all the descendants of that prince's father were declared entitled to wear a yellow girdle and to receive a pension from the state; while, with a view to prevent their becoming a danger to the dynasty, they were excluded from civil or military employment, and assigned to a life of idleness. This imperial colony was, and is still, one of the most peculiar and least understood of the departments of the Tartar government; and although it has served its purpose in preventing dynastic squabbles, there must always remain the doubt as to how far the dynasty has been injured by the loss of the services of so many of its members who might have possessed useful capacity. They purchased the right to an easy and unlaborious existence, with free quarters and a small income guaranteed, at the heavy price of exclusion from the public service. No matter how great their ambition or natural capability, they had no prospect of emancipating themselves from the dull sphere of inaction to which custom relegated them. Toward the close of Kiaking's reign the number of these useless Yellow Girdles had risen to several thousand, and the emperor, alarmed by the previous attacks, or having some reason to fear a fresh plot, adopted strenuous measures against them. Whether the emperor's apprehensions overcame his reason, or whether there were among his kinsmen, some men of more than average ability, it is certain that the princes of the Manchu family were goaded or incited into what amounted to rebellion. The exact particulars remain unknown until the dynastic history sees the light of day; but it is known that many of them were executed, and that many hundreds of them were banished to Manchuria, where they were given employment in taking care of the ancestral tombs of the ruling family.
