oh yeah this log of wood is the size of 47 of my decently-sized but still individually variable feet in length, 52 and 17/32ths of the length of my thumbnail and weighs about 833 medium sized stones with somewhat rough edges made out of compact rock composite with low levels of limestone and andesite. said rocks are not to be too big and cumbersome to carry or manipulate but not small enough to where using them as a measure of displacement would be a labouring and tedious activity. this is a logical way of measuring things
