Papa Tom and I went to San Antonio on Tuesday to sight-see before his oral surgery at the UT dental school on Wednesday. We visited the Mission Espada aqueduct, built in the early 1700s. The aqueduct still irrigates the mission's fields today. The aqueduct is ever so slightly sloped, so gravity can move water into the fields. Unused water was returned to the river in the early days, as required by Spanish law. I'm not sure if that's still the case. |
