Exhibit 4245 - Assortment of Bolus-Caches

Bolus-caches were used by members of the Covert Lexical Movement (CLM) to exchange encoded messages, most commonly stored in animal skins or neoprene bladders. Using this communicative method, CLM directors were able to exchange vital information regarding their group's clandestine operations without the knowledge of the authorities.

The discovery of the first bolus-cache in 1942, and the subsequent decoding of the message within, sent a shock wave through all branches of law enforcement. Specially trained officers as well as many vigilante groups scoured the spillways, dams, and hyrdo-electrical stations and uncovered hundreds of discarded bolus-cache containers, though all but a few dozen had been drained of their contents.

The CLM found bolus-caches to be so useful for their strategic planning that they refused to abandon this tool; instead, CLM operatives have drastically changed the shape and style of the containers that bear encoded messages. This exhibit shows only a handful of containers recovered from the field, all of which have been analyzed by experts and verified as having been used as bolus-caches by the CLM.

As part of the 1943 Pigment Prohibition Laws, any citizen caught in the possession of a bolus-cache is guilty of a gross felony and if convicted would face between 15 years to life in a waterblocking facility.
