Two workmen arrive on top of the span,
to connect the four slings that will lift the steel span.
Unfortunately, the time available for this job is limited,
and the A-frame has yet to be moved into position.

Moving the utility barge out of the way, and then moving the A-frame barge into position, has
taken a lot of time.  It is now more  than  two  hours  past  high  tide, and the water surface is
falling rapidly.  Is the A-frame hoist block still far enough above the bridge span to provide
adequate working space?  What to do?  The men are conferring on the utility barge.

It is now 2¼ hours past high tide.  The A-frame hoist is moving
downward with the falling tide.  Is there now enough vertical working
space available for the workmen to be able to wrestle the heavy slings
in place, and wrap the chains around the plate girder span as required?

The decision has been made.  It is now 2½ hours past high tide.
The tide has fallen too far, and the lifting of the plate girder span
can not  be done  on this  tide  cycle.  This view  shows that the
A-frame hoist has been pulled up as far as possible, and there
is not enough working space for placing the chains
attached to the lower end of the slings.

Dominion Atlantic Railway    Bear River Bridges    7 June 1912

There were two versions of the railway bridge across the Bear River in Nova Scotia:
the first  wooden  bridge  built in 1890 and its  steel  replacement  built a few metres
downstream,  completed  in  1913.  Both  included  a  large  swing  span  at  the far
west end of the bridge to allow ships passage to the  busy  timber  wharves  in the
village of Bear River several miles upriver.  In this view, the new (1912) bridge is
in the early stages of construction beside the existing bridge built in 1890.
The swing span is out of sight, behind the camera.

Why were expensive swing spans built into the
railway bridges at Bear River and Sissiboo River?

Bear River and Weymouth were the area's major ports.
Bridges were not allowed to block access for cargo ships.


Lumbering Played Vital Role
Bear River, Weymouth were county's major ports

The Digby Courier, 26 May 1999
...The enterprising firm of Clarke Bros. lead among the
lumber dealers of eastern Digby.  Their annual export is
between five and six million feet, beside 2,000 cords of
wood and 200,000 feet of piling.  Their lumber, about
12 cargoes per year, goes to Cuba and South America,
and is all shipped from Bear River, excepting
an occasional cargo from Digby...




Big Log Drive Arrives at Weymouth

Weymouth, June 5, 1909 — The big drive of logs for the Campbell Lumber Company, about four million feet, reached its destination at the lower pulp mill late Saturday night, June 5th, 1909.  George W. Wagoner was the boss of the drive, and he is very much elated over the success of his efforts, for it was no small undertaking.

This is the third large drive brought down from the headwaters of the Sissiboo River this year.  The first drive was one of three million feet, one million feet of which was for the Campbell Lumber, and two million feet for Dickie and McGrath.  The second drive was one of a million and a half feet for the Campbell Lumber Company.

The drive arriving here Saturday night was eight miles 13 km long and nearly one hundred men were required to bring it down the river, many of them being Micmac Indians.  The drive was brought down through fifteen water gates, and was one of the heaviest in the history of Nova Scotia.

[The Digby Weekly Courier, 18 June 1909]


In this context, "three million feet" means three million board feet,
or "three  million  feet  board  measure"  (as it would  appear in a
legal document such as a contract).

one million board feet = 2,360 cubic metres
three million board feet = about 7,100 cubic metres

A board foot was legally defined as a piece of wood
one foot long, twelve inches wide, and one inch thick.
In other words, a board foot was (and still is)
a measure of volume equal to 144 cubic inches.

144 cubic inches = 2360 cubic centimetres = 2.36 litres

The "board foot" was a measure widely used for sawn lumber,
and wood quantities in general (but not for firewood) in
the 1800s and 1900s, continuing into the 1980s.

Production  statistics,  inventories,  prices  of  sawn  timber,
and  other  business  information  about  wood  and  wood
products  was  usually  stated  in  terms  of  board  feet.

The term "board feet" (or "feet board measure") was often
abbreviated to simply "feet", as in the newspaper item
quoted above.  It was generally assumed that everyone
understood "three million feet" of logs meant
three million board feet.
