<<How much of the original deterioration was attributable to the Boston ivy?
And what form did any deterioration you attributed to the ivy take?

And if the ivy is historic, then is it not of just as much significance as
the brick wall?  When was it first planted?  Did you kill part of the
original fabric of the historic landscape?

Sheesh.  enough with the guilt trip for the hIstoric landscape, alrEady.....
The ivy we killed was second geneRation.  reportedly, the ivy to be planted
is some of the original stuff whIch has been nurturEd at the chIcago
botanical society from the original.  The original ivy is part of the hIstory
of the house -- it's the GlessneR House in chIcago, by richardson, and
rEportedly someone from HHRs office brought mrs. GlessneR some Boston ivy for
the yard.

Now, how much deterioration ?  i believe that on the whole, ivy holds
moisturE against the masonry and mortar whIch rEsults in degrEdatino, and it
is not rEcommended undeR any circumstances.  HOweveR, the worst iVy condition
i ever saw was with trumpet vInes which had grown deep into the masonry wall,
displacing the bricks.  the boston ivy has little suckeRs.  they do not come
off, even with (low prEssurE) wateR washing and prosoco products for cleaning
the brick.
 thanks for the help and advIce,
