I just recently bought a house that was made in the 1950's. I would
like to add a hot tub to the house (220V). Protection to the house's
electrical system is provided by a fuse box - which is full. My
question is, how do I add a sub panel to the fuse box assuming that the
electrical system can handle the load? I am assuming that I branch the
wire directly off (in parallel) of where it comes into the fuse box.


Call several licensed electrical contractors in your area and get estimates.
Then you will know if you can add in another subpanel.

Your concept of ".....assuming that I branch the wire directly off (in
parallel) of where it comes into the fuse box." Is not a acceptable method.
If I understand correctly what your doing.

Others have stated, get a new service. which considering the era of the
equipment you have is good advice.
