There are no locks on the doors or windows, and only one route of egress in the case of an emergency.
After reaching this point the next thing is to return to the entrance, when it is found that egress is as difficult as ingress.
For three months during each year business was suspended, and all ingress or egress except for the most necessary purposes was forbidden.
In eastern or "locked" Arcadia these heights run in parallel courses intersected by cross-ridges, enclosing a series of upland plains whose waters have no egress save by underground channels or zerethra.
The separation of the glumes, which occurs at the time of fertilization, and which permits the egress of the useless stamens after that operation, occurs only under certain conditions of temperature, when the heat, in fact, is sufficient to cause the lodicules of the flower to become turgid and thus to press apart the glumes.
