Philip Curtin dies, having taught the field how to count

Philip DeArmond Curtin died in 2009. Eltis and Richardson name his work as the foundation their atlas of the transatlantic slave trade rests on. Before Curtin, the scale of the traffic was handled with round figures that travelled by repetition, some running to twenty million and more, none of them tied to a document anyone could inspect. Curtin went to the shipping records and produced an estimate with its method attached, so that every scholar afterward could argue with his total by arguing with his sources. That is what made the field cumulative instead of rhetorical. The voyage database behind the atlas, with its record of individual ships, ports, owners and mortality, exists because he established that counting was possible and that a count could be corrected. I keep this on a Haitian timeline because Saint-Domingue took in hundreds of thousands of captives in its last fifty years, and the size of that traffic explains both why the colony was rich and why it went up.

The earthquake hit at 4:53 in the afternoon on 12 January 2010, with its epicentre at Leogane, sixteen miles west of Port-au-Prince. As many as three hundred thousand people died, among them Archbishop Joseph Serge Miot and Hedi Annabi, who ran the United Nations mission. More than a million were left without homes. At least two hundred and fifty thousand houses came down, along with thirty thousand shops, offices and public buildings, among them the National Palace and the cathedral, thirteen hundred schools and some fifty hospitals. Over four thousand prisoners walked out of the main penitentiary. Foreign governments pledged ten billion dollars. The Dominican Republic, whose relationship with Haiti is a two hundred year argument, was the first country to send help. The American military ran Operation Unified Response. A telethon fronted by George Clooney and Wyclef Jean brought in fifty-seven million dollars. Port-au-Prince stopped working as a city, and the buildings housing the Haitian state and the foreign mission supervising it fell in the same minute.

Famine became the standing image of modern Africa, and by the 1970s many states were importing the staples they had once grown. Sub-Saharan Africa combined the fastest population growth outside the West with the slowest growth in food production. Three explanations get offered. Climate is one, since Sahel rainfall stayed low through the 1970s and 1980s. Pressure on fragile land is another. The third is political, and it does most of the work, because in a great many famines the volume of food does not fall at all. What changes is price, distribution and who holds a claim on a share. War causes famine and famine feeds war. Zimbabwe kept grain reserves through the 1980s and had food security because of them; structural adjustment called reserves a distortion of the market, the government sold them for foreign exchange, and when the rains failed in the 1990s the silos were empty. Mugabe then withheld relief from districts that voted against him.

Reniel Rodriguez Ramos worked through the stone tools from La Hueca and Punta Candelero to test whether the Huecoid and the Saladoid were one people or two. The test rests on a property of stone working. Techniques for making lithic tools change slowly and pass from one worker to another by direct instruction, which makes them the most conservative part of Caribbean material culture and a steadier marker of identity than pottery, where styles travel between communities that share nothing else. If the two groups belonged to a single culture, their stone assemblages should look alike. They did not. His results showed production methods holding steady across long stretches of time and differing between the two groups, which supports a picture of the early Ceramic Age Caribbean as several distinct cultures living at the same time in the same islands. Arguments about who the first islanders were have run on pottery for most of a century. This moved them onto harder ground.
