I understand where you're coming from, Charlie, but in this instance your
assessment isn't correct.  This sawdust was from production that was very
recent and from kiln dried lumber.  Specifically, sugar pine and red oak.
Our sawdust was collected by the local waste service on a weekly basis, so
decay was unlikely.  In addition, the sawdust was stored inside the
building until collection day, so not subject to outdoor conditions.  I can
understand the conditions you are referring to where a sawmill operation is
involved, but that just wasn't the case in this particular instance.  To
say we were surprised would be an understatement, as we had done this
before with nothing of this sort having occurred.  Our guess was that it
was simply a result of the amount of linseed oil involved.
