Mnemonic

To restore order to a scattered manuscript, toss every page into the stream. The current sorts them flawlessly — each page glides to the riverbank in exact sequence, as if the water itself refuses to deliver anything out of order.
Additional thoughts
Visualize pages fanning out on the water's surface, then the stream's laminar flow nudging each one ashore numbered side up, perfectly sequential. Stream + Page = natural, effortless Order.
Quick recall
A stream delivers every page to shore in perfect order.
