Larus spp. (hybrid) A Hybrid Gull ?? The Race Rocks Taxonomy

On October 27, 2007, we received from Pam Birley from Great Britain these pictures of an unidentified gull which she had just photographed using the remote camera 5 at Race Rocks.

David Allinson has helped us with the identification:” In short, the bird is not identifiable to species…most likely a hybrid gull also with partial hypermelanism (high melanism – darker than normal plumage and/or an example of some other complex colour abnormality which has caused its legs and bill to be darker (carotenism) — caused by either genetic defect, environmental factors, and/or stress during development or moult). This bird is most likely a Glaucous-winged with Western Gull genes (or a Western Gull with Glaucous-winged genes!). However, the head seems proportionately small which suggests possibility of some other lineage (Thayer’s or perhaps Herring).

Old Bricks at Race Rocks

The bricks for the base of the flyweel were excavated from various deposits on the island. Grass grows between the bricks by 2007 Distinctive markings occur on some bricks. We hope to trace the origins.( see this file for information on the BAKER bricks.)
Clayburn Bricks were made after is 1905 and before 1930 in the first Company town in BC. Clayburn Brick Factory in Abbotsford BC.
Bricks and debris near the shore by the tower. The beige bricks were firebrick.
This page is presented to reflect some of the historic origins of the materials used in the construction of the original buildings at Race Rocks. When you examine the pictures from the turn of the last century, you can see that only the tower now remains of the original buildings. Through the years, as buildings were replaced, the old construction materials were often just pushed over the edge or left buried in the ground. Whenever we encounter these locations, we try to recover some of the materials as historical evidence for the area. We urge any viewers who may have insight into the origin or use of these materials to contribute to these files by contacting us.

6 month fouling records

A week before raising the turbine in April 2007, the outer Nereocystis growth was removed by the Pearson College Divers. Since the top of the turbine is in a water depth averaging 10 metres it is shallow enough for the brown Macroalgae to take foothold and within a few weeks it would have reached the surface. This algae can atttach to a solid substrate within the top 12 metres of water at Race Rocks.

Thanks to Russell Stothers of Clean Current and the Pearson College Divers for these images.

Against the rock wall above the original concrete foundation of the old engine room, and below the tower, a group led by Hannah and Giovanni on one Project week did the digging out of soil, and replacement with crushed rock. . This allowed the creation of a natural looking corner for the old historic engine room equipment.

Sylvia and Alex Chan examine the old engine parts. Looking straight down from the tower on the east side, one can see the concrete pathway which we believe went to the blacksmith shop. In the past, many old pieces of equipment were simply pushed over the side. In 2006,the old boiler which lay rusting in the intertidal zone for many years was starting to break up.
The storms in the winter of 2006 dispersed the parts of the boiler These pieces which are now small enough to move will be transferred to the collecting area. The other end of the boiler. This was carried up to shore on February 12, 2007 by members of the racerocks.com activity.See below. The hurricane in December 2006 moved rocks exposing more rubble below the energy building.

The last of the rusted parts of the old boiler from the engine room shown above are carried up by Pearson College students in the Race Rocks Activity in 2007 to be part of the collection of other old parts stored at the base of the tower.

Early History of Race Rocks Lighthouse Part 2

In Jan of 2007 the following article was published in the Victoria Times Colonist:

49446-15805A beacon of hope for Race Rocks
Carney tries again to win protection for prize lighthouses now withering away, Jack Knox, Times Colonist, Tuesday, Feb06, 2007. 

. Over the next two days several e-mails full of documented history came from Dale Mumford who has worked at Fort Rod Hill and Fisgard Lighthouse National Historic Sites for many years. He has provided an update which shows a different interpretation from some of the stories we had collected over the years. So to add to the documented history, we have included his comments and extracts from the original sources here. Fisgard and Race Rocks lighthouses were essentially built at the same time, Fisgard entering service just six weeks before Race Rocks in 1860. In developing exhibits and interpretive programs for Fisgard Lighthouse over the years the staff at the site have had to become very familiar with the early history Fisgard, and of Race Rocks as well. As the two lights were designed to work together, and were the only lights constructed during the colonial period, we try to explain this relationship in programs for visitors (and virtual visitors). To support this work, we have on hand at the sites copies of many original documents regarding the early construction and operation of the lighthouses. We also have an excellent two volume history of the Fisgard Lighthouse and the Early Lighthouse of British Columbia produced on contract for Parks Canada in 1980. Unfortunately as this work was produced primarily as an in-house document for Parks Canada staff, it was printed only in very limited numbers as part of the Parks Canada Manuscript Report Series and has never been widely available to the public.

Ed note: Now these publications have been digitized and are available at the following URLS:

http://parkscanadahistory.com/series/mrs/356-1.pdf -this document is on Fisgard lighthouse since it was the one being targeted for National Historic park status at the time this document was written:
http://parkscanadahistory.com/series/mrs/356-2.pdf— This is on the rest of the lighthouses including Race Rocks.

Mr.Mumford has invited us to have a look at documents in his possession so we certainly will do this in order to try to get to the bottom of what is the correct version of history of the Lighthouse. He goes on with

  • ” From these sources, we have been aware that there are a number of inaccurate stories that have been circulating for many years, and have beenrepeated in many books and articles about the original construction of these two lighthouses. It has often been stated that the lighthouses were built by the Royal Navy, and that the lighthouses were designed in Britain and the whole of the building materials were shipped to the colony. In particular with regard to Race Rocks it is often said that all of the stone was pre-cut in Scotland and shipped here like a giant lego set.
  • In fact, the primary source documents that have survived from 1858 to 1860, and there are many, make it clear that none of this is true. The British government did provide funding for the construction of the two lighthouses, (7,000 pounds, half as a grant and half as a loan), but the construction and operation of the lights was undertaken under the supervision of the Colony of Vancouver Island, (construction specifically under the direction of the colonial surveyor, Joseph Pemberton) and the lighthouses were constructed by local contractors using local materials. The only materials sent from England were the lanterns (in architectural terms the iron and glass lamp rooms at the tops of the towers) and lighting apparatus and stores. In the case of Race Rocks stone for the lower portion of the tower was initially quarried right on the island!
  • The treasury officials in providing the funding specified in a letter to the Colonial office dated April 29, 1859 “…that Sir E.B. Lytton will make Governor Douglas fully aware tht altho’ the Board of Trade will readily afford any advice or information , and will send out from this country the lighting apparatus, they decline undertaking responsibilty as to the selection of the site or the construction of the Towers…” The colonial surveyor, J. Pemberton in his original estimates to Gov. Douglas states he planned to quarry rock on the site. In the estimates dated Aug 23rd 1860 he states: ” That brick would be preferable at Esquimalt, and stone quarried on the spot, at Race Rocks, where the distance from Victoria is greater, the currents more rapid, exposure to weather more and Building stone (bluish Granite) excellent.
  • In a report of progress from April 7, 1860 he states “… that sufficient stone has been dressed to build one third of the tower, and enough stone to build the Lightkeeper’s House, and that large quantities of material & stores are safely landed at the Rock. At present there are 12 Stonecutters, 1 cook and one overseer, and on Monday the Contractor proposes to commence building the Keeper’s house.”
  • I had heard ( and I’m trying to remember from what source) that the tower was finished in sandstone from the Gulf Islands as they had run out of suitable stone on site. If the granite stone in the tower is not from the site, this represents a change in the original plans for construction, and there is no mention in the papers we have of where else it could have come from. It is clear no one ever intended to send stone from Britain for the purpose. The main source for most manufactured building materials ( including finely dressed lumber) at that time was San Francisco.
  • The ballast story doesn’t actually make any sense if you dig deeper. While all sailing ships carried some ballast, this was only removed to lighten the ship for dry docking, carreening or to get it afloat if it ran aground. Ships with no cargo took on extra ballast for the duration of their voyage, but shipping rates to British Columbia during the gold rush were amoung the highest in the world. There was a market here for every concievable comodity and it is very hard to imagine why any ship would have sailed here in ballast at that time. In over 30 years of reading about maritime history, I have never come across a reference to a ship ballasted with granite blocks or bricks. Invariably permanent ballast is referred to as “shingle” ( i.e. heavy beach stones, usually shale etc. easily shovelled ) or pig iron, so I have never bought the ballast story. I’m not saying impossible, just very unlikely and certainly unsupported by any orignal documents I’ve ever seen.
  • Mr. John Morris was awarded the contract to build Race Rocks lighthouse.John Wright built Fisgard. Along with Jos. Pembertons Surveyor General, there were five Captains in the original group of Lighthouse Commisioners that choose the specific sites in 1859; Captain Richards, H.M.S.Plumper; Captain Fulford, HMS Ganges; Captain. Moutt HBC steamer Otter, and Captain Cooper and Captain Nagle, Harbour Masters of Esquimalt and Victoria respectively. All this appears in Walbran* and . Note that Walbran does not mention anything about stone from Britain or the navy building the lighthouse. He does say the British government built the lighthouse and correctly provides the amount of the grant/loan.Richards had already identified the need for lights on the Race Rocks group and at the entrance to Esquimalt harbour in his report of Oct. 1858 which accompanied by letters from Gov. Douglas and Rear-Adm. Baynes, had first requested funding be considered for the two lighthouses, so it is sometimes stated that he chose the sites.”

” If you remain sceptical about some of this information, I can hardly blame you as many of these stories have been repeated over and over in many publications.. ”

Ed Note: It is interesting how different versions of “history” can arise over the relatively short time of 150 years. There is still some question about the rock being quarried on site. As it seems that many of the blocks of granite that are still existing from the house which was attached at the base of the tower are of grey granite. The only problem is that most of the existing rock that makes up the island of Race Rocks is a black fractured basalt, and not consistent with the type of rock of the area. So the jury is still out on that one until we can determine the type of stone at the base of the tower. (More on this later!)  There are several examples of Imperial Lights in the British Empire being built with granite from Great Britain. eg. in New Zealand and in South Africa.

An additional note on the history page also confirms that the crew from the British Naval vessel Topaze assisted in the building of the tower.

On the Canadian Coast Guard Site in “USQUE AD MARE,–A History of the Canadian Coast Guard and Marine Services by Thomas E. Appleton” further support for the theory of the granite rock coming from Britain is included:

  • “Between this time and Confederation many light stations were built in Canada, mostly of wooden rather than stone construction, as this was cheaper and more suited to the needs of the country; among notable exceptions, the Race Rocks light tower in British Columbia was constructed of stone which had been quarried and cut in Scotland and sent out by sailing ship around Cape Horn.”
