Hatch security

The hatch locking mechanism is perhaps the most important part of hatch security. There are a number of locks that can be implemented for hatches, including the following ... 

The larvae that hatch from Cotesia eggs remain inside their caterpillar host, exploiting it as a secure haven from the outer world and a convenient food supply. They feed on the caterpillar from within until they are mature and ready to pupate. Then they emerge from its body and immediately begin spinning small white cocoons, which they attach by one end to the caterpillar s back. It is not uncommon for a tobacco hornworm, still alive, to be festooned with fifty or more Cotesia cocoons, each resembling a diminutive grain of rice fastened to the caterpillar. Each cocoon contains...

Smoke abatement was a staple topic of municipal reform movements in the late nineteenth and early twentieth centuries, and many American cities, especially Midwestern industrial centers where the problem was most severe, adopted control ordinances.
