It was time to pack up and leave. Shofiq, who is from Sylhet, was dropped off near his home and the fellowship of the rocks was broken. We settled in for another long drive. We made an impromptu stop at one of the numerous brick factories scattered across Bangladesh. Here, the workers immediately started snapping pictures of us with their phones. We walked past the rows of drying unfired bricks to the massive kiln built from the bricks themselves. We saw them feeding coal into the hot, actively firing part and unloading bricks from the completed quadrant. This would be followed by loading of raw bricks for the 12-hour firing. This factory makes around 9,000,000 bricks in the six-month season. Although it was their lunch break, they demonstrated the mixing of the mud with a little sand and let me carry a half-full wheelbarrow load to where the bricks were
shaped. I spilled a full load when I tried to move it. The experienced brickmakers took about 30-seconds per brick.
We stopped for lunch at the same roadside restaurant, then went to find Wari-Betashwar. Getting to the archeological site was not easy, but a mixture of my hand-held GPS with a Landsat image and a Bangladeshi phone with completely inaccurate Google maps eventually got us there a little after 4 p.m. We toured the site with the chief archeologist, but all the excavations had been filled in to protect them during the off-season. As we walked around the 600m by 600m protective wall, Prof. Rahman explained the history of the site. This urban
center was founded around 500 BC on land slightly uplifted by one of the anticlines. The slight extra elevation protected the land from flooding. The site was by the side of an old path of the Brahmaputra River and was thus a major trading center. Artifacts from as far as Greece and Rome were found here. After a gap in the record, the city flourished again in the 7th century AD, before being abandoned. The rise and fall of the center may be tied to avulsions, or switches in position of the Brahmaputra, making the site an interesting confluence of tectonics, rivers and people.
Continuing on, the students got a taste of Dhaka traffic as we approached our hotel near the airport. Now came the real
splitting up of the group. The foreigners would stay overnight to begin our return home, while the Bangladeshis would fight the traffic to return to Dhaka University and their homes. Many of us spent most of the time until our 2:30 a.m. departure talking. Twenty-three of us and our luggage and equipment managed to squeeze into a 21-seat bus and made it to the airport. Now, once again problems with our tickets arose. While most of us were fine, almost half only got boarding passes as far as Abu Dhabi, or none at all. Eventually they fixed the problem for most of them, and all of us were able to board the delayed aircraft. The delays here and in the flight to New York and Chicago will mean that the vast majority will miss connections. At least my nightmare scenario of missed flights and connections was happening on the way back. Not the smoothest ending, but it has been a great trip and a very successful field school. Several of the students are trying to figure out how to get back to Bangladesh, and a lot of lasting friendships and connections have been made.
