5. Obö. "A heap of stones on which every traveller is expected of
his piety to throw one or more as he goes by." (Jülg.) Abbé Huc
describes them thus: "They consist simply of an enormous pile of
stones heaped up without any order, surmounted with dried branches
of trees, while from them hang other branches and strips of cloth on
which are inscribed verses in the Tibet and Mongol languages. At its
base is a large granite urn in which the devotees burn incense. They
offer besides pieces of money which the next Chinese traveller, after
sundry ceremonious genuflexions before the Obö, carefully collects
and pockets. These Obös are very numerous."
