In 1995 Texas Historical Commission (THC) staff and a team of researchers discovered a shipwreck in the mud of Matagorda Bay. Preliminary artifact recovery included a decorated bronze cannon that identified the wreck as la Belle, the fourth and final vessel of the ill-fated venture to found a colony on the Texas coast by French explorer Robert Cavalier Sieur de La Salle. A full excavation of the site was conducted in the following years. Among the items recovered was an intact chest (Artifact No. 11500) which at the time became known as the Belle Mystery Chest. Initial inspection revealed that the chest was most likely a repository for various tools, but further work revealed a sundry collection of artifacts. Subsequent artifact analysis determined the tools to be instruments used in a variety of occupations ranging from that of French wine coopering to those of agricultural, military, and maritime endeavors. Historical research primarily using the firsthand reports from the expedition??s survivors suggest the chest was first boarded in France on one of La Salle??s other ship??s, l??Aimable, unloaded prior to that vessel??s wrecking at the mouth of Matagorda Bay, taken to the new settlement by way of la Belle, and eventually returned to the ship just prior to its sinking. Records verify that La Salle often claimed the possessions of the dead and that he ordered the ship reloaded with his personal goods and other supplies before it sank. Along with two artifacts with differing ownership initials and the sheer diversity of the chest??s contents, these clues suggest that the chest may have been a repository for various utilitarian items collected by La Salle before the loss of la Belle in January of 1686.

The Wabash Valley Seismic Zone (WVSZ) has produced three moderate sized earthquakes greater than or equal to mb 5.0 in the past 50 years. The majority of Wabash Valley faults originate near the junction of the Rough Creek and Cottage Grove faults and extend northeastward along the Wabash River. These faults extend through the Paleozoic and into the Precambrian and are believe to be associated with the Reelfoot Rift. Two of these moderate sized earthquakes have occurred north of the terminus of the Wabash Valley faults that the WVSZ is commonly associated with. This suggests that other sources of seismicity exist. The La Salle anticline, a Precambrian basement feature, is oriented NW to SE just north of the termination of these faults. The La Salle anticline creates up to a 750 meter uplift in the above Paleozoic strata. This uplift creates faults within the Paleozoic strata and within the La Salle anticline. This study uses seismometers arranged in a phased array near the southern terminus of the La Salle anticline to analyze the seismicity of the region. Analyzing the seismicity of the region over a 6-month period found 834 events. The vast majority were determined to be mine blasts or otherwise human induced. Two small earthquakes (~M 1.0) located near the La Salle anticline. These earthquakes likely occur on faults associated with the anticline. The lack of earthquakes suggested the b-value of the La Salle region could be as low as 0.56. This is lower than the typical value of 1, but consistent with other intraplate regions and previous studies of the WVSZ finding values nearer 0.7.

Thesis (M.A.)--Boston University / Jean-Baptiste de la Salle, who was to effect great progress in the elementary education for poor boys, was born at Reims, France, on April 30, 1651. Throughout his early years he displayed extraordinary piety and finally, in 1678, was ordained a priest. From boyhood until his ordination, la Salle had hoped and expected to live a quiet and scholarly life, filled with meditation and prayer. But the untimely death of his parents, which necessitated his return to Reims from Paris (1672), was to reveal quite a different role for him to play in life. La Salle had returned home to assume the guardianship of his brothers and sisters. As his spiritual director, he chose Father Nicolas Roland, a young man greatly devoted to the education of an orphanage of girls. However, the young priest soon died, and la Salle unwillingly devoted himself to directing the teachers of the orphanage and obtaining legal recognition of the teachers as a group. [TRUNCATED]
