“B seven. G twenty-four. O eighteen.”

As the announcer neatly ticks off the options that could let you take home that BINGO prize, the apparently random assortment of numbers in front of you begin to take on shape. Patterns emerge and your excitement increases with every square that connects. But, as any seasoned BINGO player will tell you, listening for the next one is as important as marking down the ones previously read. If you fall behind because you over-celebrated getting the second to last block, you may miss the announcement of your winning square. Finding what the pattern looks like, seeing the gaps of what you need next, and paying attention are, in my view, the fundamentals of BINGO.
​ 
As it happens, these could also be considered the fundamentals of my experience this past semester in Professor McNeill’s Environmental History Seminar. 

Professor McNeill began the seminar asking all five students to nominate themes for discussion throughout the semester. The topics suggested ranged widely, from “Big History” and “Energy” to “Urban Metabolism,” showing the varied interests and priorities of the room. As a newcomer to environmental history, the full blackboard and resulting skeleton syllabus was my first exposure to a summary of which historical themes might mesh well with environmental thinking. As it turned out, that appeared to be pretty much anything – a random assortment of topics to an inexperienced eye.

​As the semester proceeded, patterns emerged. Historical and environmental questions blended together and grew from class to class. What does it mean to write accessibly? What about scientifically? What do we, as both historians and readers, gain from including and exploring the materiality of our subject matter? Some were more detailed (what is copper, bison, or soil, anyway?) and some were much bigger (should every history start with the Big Bang?). 

With each new idea, every class encouraged a reassessment of your own work with a fresh environmental perspective or a new method. The weekly exercise of identifying “grist for your mill” encouraged us to layer concepts on individual projects, paying attention to what’s out there and assessing how it had been applied. Reading, listening, thinking, and debating the way through each book created more informed views of what gaps existed. 

Inspired by the spectrum of interests and the mini-reflections throughout the spring, ECO-BINGO tried to capture the semester’s patterns in twenty minutes in the last class. Each square represented a topic covered in the course. As Professor McNeill read the topics in a random order, each student used their own ECO-BINGO sheet (all of them different) to mark the ones they found personally useful for their ongoing studies. Just as in the regular version, if the student got BINGO, any square marked had to be justified – in this case by proving to the room how it would apply to their project in the future. With the addition of visitors to the class, two PhD candidates and one who had successfully defended, to serve as judges, the pressure was high for succinct, thorough, and compelling reasons that, say, “Animals & Grasslands” would be important to your research.

ECO-BINGO served as a fun way to rehash the topics of the semester, but the reflective process struck me as a reminder that, as scholars, we benefit from continually reckoning with our own projects in light of new input. Historians search for patterns in their research, both relying on existing work and uncovering opportunities for study. To be able to do that work requires constant exposure and seeking out ideas, which the classroom setting in the Spring fulfilled so well. I was glad to have registered and now find myself incorporating environmental themes into my own work going forward.
​ 
Which reminds me that the other known fundamental of BINGO is a little luck.

In fall 2016, Michal Polczynsky, a Georgetown alumnus who studies the medieval history of the Black Sea region, invited history grad students to bring a digital copy of an archival document to his GIS workshop. I brought along a scanned page which showed a detailed map of the Canada-US border between Lake Huron and Lake Erie. While we took copious notes, Mich explained how to turn our scanned documents into a semi-transparent ’layer’ that could be superimposed over a modern satellite map, almost like laying two overhead transparencies on top of each other. We linked the current and archival maps by identifying points that were common to both. For example, the city of Detroit was on my archival map and on the modern satellite map. Since the archival documents were rarely perfectly accurate, they tended to look rather stretched and odd once we had done the work of linking these matched points (see photo). However, it was fascinating to see where the historical mapmakers had been mistaken, and in Mich’s work, the combination of satellite imagery and medieval maps had enabled him to locate long-destroyed fortifications and buildings with precision.

The Lakeview No. 1 gusher was one of the largest oil spills in the United States’ history. In eighteen months, 9.4 million barrels of oil gushed from the well, more than twice the 4.4 million barrels of oil that spilled into the Gulf of Mexico in 2010 and more than ten times the 900,000 barrels of oil spilled at Spindletop, a famous gusher in Texas, in 1901. ​

​During the first half of the twentieth century, oil spills of such magnitude were not mourned as environmental disasters but celebrated as harbingers of oil wealth and material progress. The Lakeview gusher may have been short lived, but oil production in nearby oil fields was enduring. 
 
Lakeview No. 1 sits atop the Midway-Sunset oil field, the largest among a series of giant oil fields that were discovered in West Kern County between 1889 and 1911. The discovery of these oil fields set off a huge boom in commercial oil production that made California one of the most prolific oil producing states. In 1893, California was producing only 470,000 barrels of oil per year, but by 1910 the state was producing 73 million barrels of oil per year and its production accounted for more than one fifth of total oil production worldwide. During the following decade, California became the leading oil producer in the United States and Midway-Sunset alone was responsible for half of the state’s oil production. Oil companies erected thousands of wooden oil derricks across West Kern County and by 1923, California’s oil fields accounted for a full quarter of oil production worldwide. ​

​The West Kern oil fields remain some of the most productive oil fields in the country. In 2016, California ranked third in oil producing states, behind Texas and North Dakota. Midway-Sunset is the largest oil field in California, producing 24.7 million barrels of oil in 2016. The top five oil fields in California are from West Kern County and in 2016 these five fields alone accounted for 52 percent of California’s oil production. ​

​The site of the Lakeview No. 1 gusher and the Midway-Sunset oil field are testaments to this distancing. Except for the plaque commemorating the well and the message board that recounts the site’s history, the dusty depression of the once-prolific gusher is otherwise indistinguishable from the surrounding desert. More noticeable from Highway 33 is the forest of oil pumps that stretches as far as the eye can see in some places. But I grew up in California and know few other Californians who have ever driven down highway 33 and fewer still who would recognize the name Midway-Sunset or the historical importance of the West Kern oil fields. ​

​In 2014, my family and I visited the oil fields. As I stared out the window at the industrial landscape of steel pipelines and oil pumps unfolding across the desert in front of me I struggled to reconcile how this foreign and forbidding landscape was at the heart of a standard of living I have come to take for granted. After visiting the site of the Lakeview No. 1 gusher and stopping to take photos of the Midway-Sunset oil field, we concluded our trip at the Western Kern County Oil Museum in Taft. The local chapter of the American Association of University Women established this amazing museum in 1974 when it rallied to save the last of Kern County’s wooden derricks. The site has a wealth of information about the history of the oil industry, both local and worldwide. ​

​Skies raining blood, clouds catching fire, and beasts running amok—a surreal mix of fact and fantasy, the kind of which only a malnourished graduate student could conjure up before drifting off to sleep in a cold, dim library.
 
The Ottoman scholar Katib Çelebi (d. 1657) would beg to differ. The setting for these disturbing images, he reported in his chronicle Fezleke, was Hungary in late June 1619, soon after the breakout of Europe’s Thirty Years’ War. The story is loaded with enigmatic symbolism that I dare not explain, at least not today. Below is a rough translation of the Ottoman text based on the version found in Mustafa Naʿima’s (d. 1716) chronicle, whose prose in this passage is a bit clearer than Çelebi’s.

 
We can all agree that the story doesn’t make ecological sense. The sky, needless to say, doesn’t rain cannonballs, regardless of how much they weighed. We can also agree that the mental stability of Katib Çelebi, one of the most accomplished Ottoman intellectuals of his time, is beyond question.
 
If our premise is true, what do you make of the story?

For my purposes, Mueller's interactions with the Mediterranean world included frequent dispatches of eucalyptus seeds to Algeria, France and Italy, and interchanges of scientific information, in both private letters and published journals, with institutions of science. Scholars of North Africa will find complete runs of the Bulletin de la Société d’Agriculture d’Alger (image, right) and the Bulletin Agricole de l’Algérie-Tunisie-Maroc, alongside mycology journals and numerous volumes of Linnaean societies from across the European continent. Other topics with rich potential for further study include the social and bureaucratic histories of pre-Federation Australia, the exploration of Australia, Oceania and the Antarctic, networks of exchange in the Indian Ocean and the British Empire, German colonialism in Africa and Australasia, and Mueller's engagement with the theory of evolution.
