### p73 maize storehouses are carefully maintained > An important distinction should be made between storehouses and storage facilities. Maize is always stored in a storage facility, but the facility is not always in a storehouse. Storehouses are independent buildings that can be either former residences or buildings constructed especially to contain maize storage facilities. Because store houses play such an important role in the household economy, they are often built, repaired, and maintained as carefully as residences. Walls are meticulously sealed with daub in order to create a stable and secure interior storage environment. On the other hand, maize storage facilities are either cribs or bins (trojes) both of which are elevated rectangular structures constructed from wood poles. The only difference is that bin interiors are generally lined with guano leaves while crib walls are open to allow for air circulation - [[Domestic Storage Behavior in Mesoamerica#p73 maize storehouses are carefully maintained|View in Vault]]
