An interesting exercise.*  Spruce clearly splits with reasonable ease from the butt end, if the length is less than the distance to the next whorl.  That is, it splits with no more or less grace than red maple.  Nowhere near as easily as ash or birch, nowhere near as impossible as elm.  This means you could, if you liked sparks, create billets for a stove or campfire without killing yourself (you wouldn’t be having fun though). 

What spruce does not do is split lengthwise for rails.  Splits stop at the whorls and the sufficient number of crossing fibers makes getting the wedges back out a bit of a nuisance.  There is a reason you always, always keep one wedge free.

I think we shall now go hack it up into movable hunks.
