Hole In The Wall

Saturday, February 6, 2020

Saturday proved to be one of the coldest hike days of the year so far and we determined not to set ourselves up for too long of an excursion.  Arriving with two cars, we parked one beside the town hall in Limehouse.  The second car we moved to the point where the Bruce Trail crosses the 4th Line.  With fresh snow on the ground, it is always interesting to see the tracks of the animals we share the trails with.  This small set of tracks includes drag marks from the tail of the mouse that made them.

The Bruce Trail is a resource that many people seem to ignore in the winter months but each season has its own special beauty.  We saw very few other people until we reached the Limehouse Conservation Area, where dog walkers were taking advantage of the sunny day.

The first school in Limehouse was one room made of log construction.  It was replaced in 1862 with a one room stone building.  When the lime industry was prosperous the town grew fast so that by 1876 there were three hotels and three general stores.  That year, 4,130 tons of lime and lumber was shipped from the railway station in town.  A second floor was added to the school in 1875 but it was only used until 1890 when it was closed.  The room was opened again in 1954 and remained in use until 1962 when the school was replaced with a new one.  Today the building serves as a private residence.

Acidic water breaks down carbonate rocks such as limestone by dissolving them.  This process is known as karst and is common throughout the Niagara Escarpment.  For more detailed information and pictures of this please visit our post on Eramosa Karst.  At Limehouse the Bruce Trail passes through a section of karst known as The Hole In The Wall.  Stairs allow you to access the bottom of these cracks in the limestone.

In 1917 the Toronto Suburban Electric Railway arrived in Limehouse with a stop on the 5th line at the foot of what is locally known as Gibraltar Hill.  The stop was convenient because it was located between the school and the heart of town.  The old line can still be traced from Georgetown through to Guelph by looking at Google Earth.  The rail line passed through the middle of the mill pond on a trestle.  Three rows of pilings for the trestle can still be seen crossing the drained pond.

The lime mill was built by John Newton who took the burnt lumps of limestone and ground them into powder.  This was then “slaked” with water and mixed with sand and cow hair.  The resulting mixture was used as mortar in construction.  The mill ruins and the remains of the stone arch from the tail race are all that is left.  These have been deteriorating from people climbing on them and the arch has lost several rows of stones.  They have now been protected behind a recently installed fence.

The big innovation in lime kilns came with the creation of the draw kiln.  The draw kiln at Limehouse was 16 metres high when it was completed in the 1860s.  It has since collapsed considerably in spite of restoration efforts.  Several of these kilns can be found scattered across the Ontario landscape, including two near complete ones at Kelso.

The earliest kilns were set kilns where the limestone was placed in the kiln and packed in with wood.  Burning would take days and then it would be allowed to cool down before being unloaded.  There is a strip of seven set kilns that were built in the 1840s.

The powder house was added in the 1850’s to provide storage for the blasting powder that was used to break up the larger chunks of limestone.  Blasting was discontinued around 1917 as the quarry had expanded to the point where the local residents feared the explosions would damage their homes.

Limehouse is one of our favourite places to explore because there is so much history that has been retained.  Fortunately, the local historical society is actively working on preservation of the kilns.

Limehouse

Saturday June 20, 2015

It was a beautiful morning at 16 degrees with just a trace of clouds in the sky.  We set out for the village of Limehouse which is situated on the Black Creek, a tributary of the Credit River.

The village of Limehouse started off known as Fountain Green.  Limestone was easily accessed near the surface and was needed for mortar for construction materials.  By 1840 there were two separate lime manufacturing sites in the village.  When the Grand Trunk Railway came to town in 1856 the means of distribution came as well, and the industry expanded quickly.  Soon it was employing over 100 men in a 24 hour business.  The following year the town got a post office and took the name Limehouse.

The first mill in Limehouse was a saw mill built in 1820 and operated by Adam Stull.  The mill was owned by several people over it’s 120 year history before finally closing in the 1940’s.  The steel flume that carried water to the saw mill turbines is a later addition, likely sometime after 1900.

The earliest lime kilns were the set kilns of the 1840’s which could burn 6 to 30 tons of rock in a 7 day cycle.  Lime would be added in along with wood and burned.  Wood had to be added through the sides for three or four days to keep the heat up.  The oven then needed a cool down period before the lime could be removed.  Set kilns were often built in rows or clusters. The one pictured below is part of a row which has two larger kilns on either end and five smaller ones in between.

Blasting powder was used to break large chunks of rock out of the quarry.  Around 1850 a powder house was built in a slight depression on the quarry floor.  It was located here to limit the damage it would cause if there was ever an accident.  The walls are made out of limestone with a plaster coating on the outside.  Inside it would have had wooden shelves to store the dry powder on.  The powder house had deteriorated to half it’s height but was restored in 2004.

Along the trail from the Powder House to the mill ruins grow woodland strawberries. Strawberries are members of the rose family and as such are not true berries.  Wild strawberry plants have been cultivated to grow the large plants with large juicy berries that we see commercially.  Wild strawberries seldom grow larger than 1 cm but they pack a lot of taste in a little bite.

In the 1860’s a new style of kiln called a draw kiln was developed that could burn 6-18 tons of limestone per day.  The example in the picture below was 16 metres high and has four fireplaces on either side.    It was constructed of limestone masonry with a double layer of fire brick inside.  It took a day to heat the kiln up but after the interior was hot it could be run continually.  Limestone was fed in from the top, which was level with the edge of the quarry. The burnt lime was removed from the bottom of the kiln.  In 2009-2010 the fireplaces, where the fuel was burned, were restored but the fire brick lining from the stack of the kiln has since collapsed into them.  The rest of the kiln is braced to prevent further collapse until it can also be restored.

Extensive ruins of the Lime-Mill cross the Black Creek just below the old mill pond.  The lime mill ground lime in much the same way a grist mill ground grain. This arch is an original feature of the mill race.  Older photos show at least two more rows on the top.  The Halton Hills Branch of the Architectural Conservancy Ontario asks that people please keep clear of the arch to assist in it’s preservation.

The Widow Skimmer is a species of dragonfly found in Ontario.  The adult female has a yellow striped body and both sexes have black bands on the wings.  A dragonfly can be distinguished from a damselfly because it sits at rest with it’s wings spread open.

In 1917 the Toronto Suburban Railway (TSR) came through Limehouse on the way to Guelph.  It passed over the mill pond and crossed the 5th line where there was a small station.  The railway was closed in 1931 and the railway pilings remaining in the former mill pond are about all that remains.

Limehouse has a series of caves and cracks that have become known as the Hole In The Wall. We climbed in and out of them in several places.

An upper mill stone, also known as a runner stone lays face down along the trail just beyond the mill ruins.  This stone was turned using the iron hook in the middle.

The coach house behind the church likely dates to 1876 like the church building it served. Parking has always been a problem and is made even worse when your vehicle is a horse.

IMG_5772

The Methodist Episcopal Church in front of the coach house was built in 1876.  I can find no explanation for the word Horeb on the front of the church.  The Methodist congregation had been meeting in the Limehouse Presbyterian church which also housed the Episcopalian congregation before they moved into their own building.  The Presbyterian church was frequently referred to as the Limehouse Union Church, much like the chapel in Dixie.  We didn’t stop to photograph the 1861 Presbyterian church on the edge of town because of a two car crash in front of it’s cemetery.  I was in less of a hurry to get in than they were, or so it seemed.

IMG_5775

Limehouse had three hotels in it’s heyday.  The one in the picture below belonged to Miles Mcdonald who was a local carpenter.  He also built the Prebyterian church just up the street, helping it to open debt free in October 1861.

IMG_5779

The fire of 1893 that destroyed the woolen mill and blanket factory as well as a paint factory gave the town a major setback.  Lack of insurance led to the industries never being rebuilt.  The quarry was getting closer to the homes in town and so by 1915 the lime industry was closed down.  A major industrial hub was left to quietly decay.  The Credit Valley Conservation Authority purchased the area in 1967.  Since then they have begun raising funding for restoration with some projects already complete.  Interpretive signs are being added as well.
