  We have carefully examined all the points raised by Drummond in his response
hep-th/0608109 to our paper hep-th/0606265 wherein we had made some criticisms
of his earlier work hep-th/0411017. We concede that Drummond is correct in
claiming the non-existence of R^{-4} and R^{-5} order effective string actions
in the parity conserving sector, though only insofar as equivalence of field
theories is considered at the classical level; the situation in unclear when
quantum equivalence is taken into consideration. We still maintain the
existence of such terms in the parity violating sector. Nevertheless we point
out that all this has no consequence for our original proof of the nonexistence
of order-R^{-3} terms. Apart from this we refute Drummond's claims about our
alleged use of field redefinitions as well as his criticism of our dropping
R^{-4} terms in our analysis. We reject his contention that our work is merely
a partial reconstruction of his original results and that our work contains
technical and conceptual errors. We do acknowledge the importance of the
absence of terms pointed out by Drummond.
