There was a tarantula and a pet snake that kept escaping
from their glass enclosures and terrariums. Students were always searching for
them and finding them in strange places, dehydrated and hungry. Mary was always
looking for someone to care for her many pets during vacations and to water her
many plants which together resembled a giant Venus fly trap.
There were collections of pressed leaves and flowers
gathered from the many trips around Lowndes County and the state of MS. An assortment
of rocks stockpiled from trips to caverns was assembled by a few passionate amateur
spelunkers who collected them during cave adventures. Soil samples, worms,
moths, butterflies, cockroaches, and other insects, live and preserved, were gathering
dust and making babies in dark places, in boxes all over the lab, and in the
storage area.
Students were taught how to be responsible humans by doing
two hours of work service a week for a specific teacher, a lab, or to clean the
dreaded bathrooms and hallways. When they had to clean the nasty bathrooms,
they were always more careful not to make them really dirty to begin with. Not
hiring full time janitors also saved the school money. Some students got cushy assignments;
they just had to help a certain teacher grade tests. Others were not so lucky.
Mary was a fantastic teacher and motivator and students
loved her but, doing work service for Dr. D, was not exactly an easy assignment
as students often had to clean the lab, the tools used, the beakers, and other
glass jars. Cleaning the lab was a nightmarish proposition as nobody knew if
the caged pets were loose or safely latched.
One day students had to clean cardboard boxes laden with
former students’ projects, tightly taped and not labeled. Mary and a crew of
four students were opening these boxes, like Christmas presents, never knowing
what mysterious project would be inside, salvaging any glassware contained
within, and throwing the rest in a large trash bin.
But one box was unlike the rest. Imagine the protagonists of
the movie “The Mummy,” being chased by millions of beetles emerging from the
sand and devouring everything in sight. Once this box was opened, hundreds of
cockroaches began flowing over everywhere, on the floor, chairs, tables, and
pretty much any surface available, including the soles of a female student who
was wearing sandals – the roaches crawled in between her feet and the sandals.
The students were paralyzed with fear and screaming from the top of their
lungs.
Mary jumped into action, closed the two lab doors, and emerged
from the storage area with two very large bottles of Raid. She sprayed them
copiously into the air as if they were perfumed air fresheners. Laughing
copiously as she twirled with the two spraying containers in hands, she
reassured the students that “everything was fine.” Choking on Raid fumes,
chemicals that no human should have breathed in a confined space, students
followed the leader, a farm boy raised around pesticides who had more common
sense, and fled the room. We can only hope that the escaped tarantula and other
live pets in the lab made a good meal of some of the cockroaches killed by the
Raid assault.
No matter how hard Southerners tried to exterminate this
pest every month, cockroaches thrived because they survived on very little,
like the book binding glue or their own excrement.
Mary passed away a few years later, a victim of metastasized
melanoma, and I often wondered if her cancer marker was genetic or
environmental. She had certainly exposed herself to so many chemicals on the
farm in Woodland, as a graduate student working on a Ph.D. in Biology, and during
her teaching career of twenty-two years. Students will always remember her with
fondness, her scholarship, kindness, dedication, and infectious smile.
