The southeastern well and pump house - drilled 1918.
Historical research in support of an archaeological project is characterized by frequent dead-ends, false leads, and dealing with holders of records with priorities far removed from the target of our investigations – the DSCQHR site. I am pleased to report that a partial success has been achieved in establishing some dates for activites directly related to features on the DSCQHR site. I am even more pleased that this information comes to hand from the records of the Dominican Sisters themselves.
Before moving into further detail, however, it is worth pausing for a moment to consider why historians and archaeologists, when working historical archaeological sites, really need each other.
The historical data I have derives from the DSCQHR treasurer’s account ledger for expenses since the congregation located to San Jose. I was specifically interested in determining the dates for any activity related to drilling water wells on our property since one such well may still be clearly seen on the property to the south and east of our assigned reasearch area. Furthermore, the 1897 Sanborn map provides interesting details regarding the arrangement of water storage and the transfer of water between Linda Vista Winery and the DSCQHR complex. It was further hoped that obtaining some valid dates for the well activity might indicate possible dates for the macadam asphalt features that hold promise to give a solid date for the site’s strategraphic sequencing.
Here are my notes from the DSCQHR ledger courtesy of Sister Evangela:
In 1914, a San Francisco well-drilling company drove two wells on the property, one to a depth of 63 feet and a second to a depth of 68 feet. These wells utilized three high power motors (one presumably served as a back-up in the event a primary motor failed).
In 1918, a San Jose Drilling company drove a 105 foot well and installed an new pump and motor.
In 1923, the ledger records, “well capped and one moter sold.”
In 1931, well and pump destroyed by storm.
Having walked and surveyed the DSCQHR site, and knowing of the location of the well on the southeastern section of the property, these ledger enteries were slightly puzzling: the southeastern well definitely matched the 1918 entry for there is a San Jose Motor Co. motor still on the floor of the pumphouse; however, there was no sign of any other capped shafts for the 1914 well. Furthermore, why would a well be capped within the span of five years?
I set these notes aside and drove north to the make-up day lab where the cataloging of our assemblage is proceeding. Here I discussed these ledger entries with Professor Hartley.
He held the missing key elements for a more clear interpretation of the DSCQHR ledger data. Prof. Hartley and David B. had met with Curator Galvan last week in order to determine the fate of the human tooth excavated the preceeding week. During this meeting, Prof. Hartley and David B. explored the extreme northeastern area of our general site (immediately north of the concrete foundation). There, among other interesting elements, they located the likely remains of the pylon and wood-joist foundation for a large water tank.
Archaeology is really the most fascinating and rewarding of intellectual team sports, if I may be permitted to word the activity this way. I was busy torturing the historical evidence by cramming all the wells into the southeastern site (hydro logically unsound). I did not immediately grasp that there were multiple wells using the similar technology at different locations on the DSCQHR property. Reviewing and correlating my data against Professor Hartley and David B’s report achieved a much more valid result. Thus, to summarize:
It appears that in 1914, two wells were drilled in the northeastern sector of the DSCQHR site to depths of 63’ and 68’ respectively. It is likely that these were the wells capped in 1923 (giving them about a ten year useful life). The southeastern well was drilled in 1918 by the San Jose company and this is the well that was destroyed by storm in 1931.
Here is a possible general location for the 1914 wells immediately north of the concrete foundation (based on information proved by Prof. Hartely and David B.). As a side note, the slope marked A is steep enough to allow for sheet-wash deposition of materials from A to the area marked B (an observation also made by Prof. Hartely and David B.)
Water, and particularly the engineering of getting water, is of immense importance to understanding and interpreting aspects of California history and the picture emerging at the DSCQHR site is quite vivid. It is likely that these hydrologic artifacts relate to other activities that have modified our site substantially, perhaps even suggesting the date range and purpose for the macadam surfaces unearthed during the course of our dig.
In developing a working hypothesis for the macadam, it appeared plausible that the asphalt system dated to the early 20th century and, given the method of construction, was not later than the 1920s. The DSCQHR well drilling activity was concentrated in the years 1914 and 1918.
It would be useful to determine if the artifacts found below the macadam layer antedate 1918.
