Despite the fact that Mohenjo-daro is of world-wide interest, and is such a rich field for discussion and speculation, until recently only two books had been written giving an authoritative account of the excavations, and the remains and the culture which they disclosed. These have now been joined by a third, namely, Dr. Mackay's full-length monograph on the excavations from 1927 to 1931.

When one has viewed the excavations, and read the works of Sir John Marshall and Dr. Mackay, and one realizes the immense amount of hard work and scholarship which has been lavished on them, it seems petty and churlish to raise the carping voice of criticism. Mohenjo-daro is not easily reached, and once the traveller has arrived there, without a well-prepared scheme of provisioning it is a difficult place in which to maintain oneself for a period of days while engaged in study. The fact that the available works of authority are so few and the visits of competent observers so rare makes it necessary that some more independent voice should be heard, even though it be a critical one. Without this, the few works would gain an almost Biblical authority and infallibility; this would be most deplorable, as it is almost always the least fortunate observations that secure the most frequent repetition. There is another point also which often escapes attention, and that is the relative proportion of certain objects, styles, and fabrics to the whole, stress being laid on them often in such a way as unintentionally to mislead the student and to give a false impression of quantitative importance.
