Since
that winter of the past, Anders had learned the trade of stone mason; a
“stonecutter” (stenhuggare)
they called him. This is normally a skill one learns through apprenticeship of several years,
but Anders had picked up his knowledge in a somewhat unorthodoxed way. He had
worked for about a year and a half with an older man who had been making footings for several new train rail bridges.
The
man’s name was Lars. He had been a friend of Anders’ father, who had died
several years before that time, even before the starvation winter. Anders was quite
small at the time of his father’s death, but he remembered it well. In fact, it
was one of the memories that kept coming back to him this winter. It was not
long before Christmas in that year of long ago that his father had died.
The
stonemason Lars had also been a friend to the entire family for years, and, although
he lived in a different province, he tried to help out the best that he could
after the death of Anders’ father. To be honest, this no doubt was one of the
reasons that Lars had taken on young Anders to help him on the bridge footings.
But
the other part was that Lars did need help with this project. He really was
getting quite old, and should not
have still been doing this work. Stonemasonry is a very physically demanding
job, and because of his age, Lars now cut and set the stones only with the
greatest of difficulty.
Despite
the name of stonecutter, there is no
actual
cutting of the stone involved, as with a saw of some kind. The basic tools of a stonecutter are the mallet and the chisel. Some variety of these two tools, along with a metal straightedge, is what the stonecutter uses more than any other.

There
are some other necessary tools of the trade, of course. Among these are the
steel plugs and the likewise steel feathers that are used for splitting a rock
along its line of cleavage. But all of the tools are all hand tools. They are
physically demanding tools. Added to this difficulty is the very great weight
of the stone itself. It all adds up to work that will make a man dead tired by
nightfall, even if the days are the short winter days.
This
demanding physical aspect of the work was the reason that Lars had Anders do as
much of it as the lad was able. It was because of all of this hands-on practice
that Anders had picked up the skill so quickly. However, it must also be said
that Anders had the inclination for this type of work. He was more or less of a
perfectionist by nature; and doing things accurately is a necessity in cutting
and laying stone.
This
is especially true when it came to laying up stone without using mortar. Much
of the work of a stonecutter was of this type. Stone set with mortar is a much simpler task, and requires much less accuracy
in cutting and in setting. What gaps still exist between the stones are simply
filled up with the mortar.
However,
Lars was mostly intent of teaching Anders how to build with stones without the use of mortar. Lars thought
this important for at least a couple of reasons.
The
first of these reasons is the climate, especially in the more northern regions
of the country. Stone masonry using mortar requires temperatures that remain
above freezing until the mortar is completely cured. If the wet mortar should
freeze, it weakens to the point where the mortar will completely fail, thus ruining the bond between the
stones that it is supposed to create. This will eventually
cause the building to crumble. The use of mortar was fine in the summer months,
but if the stone mason would confine himself only to those months, he would never
have enough work.
The
other point was even more important to Lars. Lars basically mistrusted mortar.
He said that he has seen too many building projects fail because of poor
mortar. Mortar is meant to bind the stone together, but he said that it often tends
to weather and deteriorate with the passing of time, leaving the rocks to
loosen.
Besides
this, the mortar-laid stone are much more
sensitive to vibrations. This is
especially important for railroad bridges and trestles. The greater the
vibration to which the stones are subjected, the more that they will tend to
loosen. If the bridge had been made using mortar, there will be much more continual
maintenance required to keep it sound and strong.

Lars
believed that fitted stones that are accurately laid are much less sensitive to
vibration. In fact, if the stone is laid correctly, the vibrations will
actually gradually work the stones to fit tighter and tighter through the
years. Some of the tightest fitted stones are ones that had been laid decades
before.

Besides
this, Anders respected his mentor too much to argue with him. And, he thought,
perhaps after he had as much experience as Lars, he too might have the same
opinion.
Anders took the role of student very seriously, deciding to learn as much as he could from his father’s friend. Any further knowledge and skills learned will be done in the years that Anders thought that he would continue with stone work. Now was the time to dedicate himself to listening and learning.

And
there was so much to learn. Young Anders learned the many practical skills
needed to cut the stone accurately and to lay them tightly together. He learned
the different kinds of rock and how to read them in order to see the cleavage
lines where they would cleanly split.
Lars
showed the lad how to read the plans for a building project, and to shape the
rocks correctly to make a strong arch or a footing. He taught him how to lift
the rocks into place by the use of a simple, home-made crane.
Anders
saw the importance of keeping his tools sharp, and to take care of them so that
they would continue to serve him well. He was a quick learner, but a careful
one. Accuracy in shaping the stone was of paramount importance to Lars, and it
became that also for Anders.
The boy owed much to his father’s friend, and
had grown to love him almost like a father.
