***UPDATE*** Thanks for all the replies***. The big 120 ft drain with 3 gutter spouts in it remains almost flat (maybe 4-6 inches of downward pitch - tops) for the first 85 ft or so. The last section is where it starts to pitch downward (another foot or so).
In Indonesia the palm-leaf manuscript is called lontar. The Indonesian word is the modern form of Old Javanese rontal. It is composed of two Old Javanese words, namely ron leaf and tal  Borassus flabellifer, palmyra palm.alm leaf manuscripts of Odisha include scriptures, pictures of Devadasi and various mudras of the Kama Sutra. Some of the early discoveries of Odia palm leaf manuscripts include writings like Smaradipika, Ratimanjari, Pancasayaka and Anangaranga in both Odia and Sanskrit.
The type of leaf is usually characteristic of a species (monomorphic), although some species produce more than one type of leaf (dimorphic or polymorphic). The longest leaves are those of the Raffia palm, R. regalis which may be up to 25 m (82 ft) long and 3 m (9.8 ft) wide.
