  "Three other scholars whose names I cannot pass over in silence, are the late Mr. R. D. Banerji, to whom belongs the credit of having discovered, if not Mohenjo-daro itself, at any rate its high antiquity, and his immediate successors in the task of excavation, Messrs. M.S. Vats and K.N. Dikshit.... no one probably except myself can fully appreciate the difficulties and hardships which they had to face in the three first seasons at Mohenjo-daro."

  The first modern accounts of the ruins of the Indus civilisation are those of Charles Masson, a deserter from the East India Company 's army. In 1829, Masson traveled through the princely state of Punjab, gathering useful intelligence for the Company in return for a promise of clemency. An aspect of this arrangement was the additional requirement to hand over to the Company any historical artifacts acquired during his travels. Masson, who had versed himself in the classics, especially in the military campaigns of Alexander the Great, chose for his wanderings some of the same towns that had featured in Alexander's campaigns, and whose archaeological sites had been noted by the campaign's chroniclers. Masson's major archaeological discovery in the Punjab was Harappa, a metropolis of the Indus civilisation in the valley of Indus's tributary, the Ravi river. Masson made copious notes and illustrations of Harappa's rich historical artifacts, many lying half-buried. In 1842, Masson included his observations of Harappa in the book Narrative of Various Journeys in Baluchistan, Afghanistan, and the Punjab. He dated the Harappa ruins to a period of recorded history, erroneously mistaking it to have been described earlier during Alexander's campaign. Masson was impressed by the site's extraordinary size and by several large mounds formed from long-existing erosion.
  
  Two years later, the Company contracted Alexander Burnes to sail up the Indus to assess the feasibility of water travel for its army. Burnes, who also stopped in Harappa, noted the baked bricks employed in the site's ancient masonry, but noted also the haphazard plundering of these bricks by the local population.
  
  Despite these reports, Harappa was raided even more perilously for its bricks after the British annexation of the Punjab in 1848–49. A considerable number were carted away as track ballast for the railway lines being laid in the Punjab. Nearly 160 km (100 mi) of railway track between Multan and Lahore, laid in the mid-1850s, was supported by Harappan bricks.
  
  In 1861, three years after the dissolution of the East India Company and the establishment of Crown rule in India, archaeology on the subcontinent became more formally organised with the founding of the Archaeological Survey of India (ASI). Alexander Cunningham, the Survey's first director-general, who had visited Harappa in 1853 and had noted the imposing brick walls, visited again to carry out a survey, but this time of a site whose entire upper layer had been stripped in the interim. Although his original goal of demonstrating Harappa to be a lost Buddhist city mentioned in the seventh century CE travels of the Chinese visitor, Xuanzang, proved elusive, Cunningham did publish his findings in 1875. For the first time, he interpreted a Harappan stamp seal, with its unknown script, which he concluded to be of an origin foreign to India.
  
  Archaeological work in Harappa thereafter lagged until a new viceroy of India, Lord Curzon, pushed through the Ancient Monuments Preservation Act 1904, and appointed John Marshall to lead the ASI. Several years later, Hiranand Sastri, who had been assigned by Marshall to survey Harappa, reported it to be of non-Buddhist origin, and by implication more ancient. Expropriating Harappa for the ASI under the Act, Marshall directed ASI archaeologist Daya Ram Sahni to excavate the site's two mounds.
  
  Farther south, along the main stem of the Indus in Sind province, the largely undisturbed site of Mohenjo-daro had attracted notice. Marshall deputed a succession of ASI officers to survey the site. These included D. R. Bhandarkar (1911), R. D. Banerji (1919, 1922–1923), and M. S. Vats (1924). In 1923, on his second visit to Mohenjo-daro, Baneriji wrote to Marshall about the site, postulating an origin in "remote antiquity", and noting a congruence of some of its artifacts with those of Harappa. Later in 1923, Vats, also in correspondence with Marshall, noted the same more specifically about the seals and the script found at both sites. On the weight of these opinions, Marshall ordered crucial data from the two sites to be brought to one location and invited Banerji and Sahni to a joint discussion. By 1924, Marshall had become convinced of the significance of the finds, and on 24 September 1924, made a tentative but conspicuous public intimation in the Illustrated London News:
  
  "Not often has it been given to archaeologists, as it was given to Schliemann at Tiryns and Mycenae, or to Stein in the deserts of Turkestan, to light upon the remains of a long forgotten civilisation. It looks, however, at this moment, as if we were on the threshold of such a discovery in the plains of the Indus."
  
  In the next issue, a week later, the British Assyriologist Archibald Sayce was able to point to very similar seals found in Bronze Age levels in Mesopotamia and Iran, giving the first strong indication of their date; confirmations from other archaeologists followed. Systematic excavations began in Mohenjo-daro in 1924–25 with that of K. N. Dikshit, continuing with those of H. Hargreaves (1925–1926), and Ernest J. H. Mackay (1927–1931). By 1931, much of Mohenjo-daro had been excavated, but occasional excavations continued, such as the one led by Mortimer Wheeler, a new director-general of the ASI appointed in 1944, and including Ahmad Hasan Dani.
  
  After the partition of India in 1947, when most excavated sites of the Indus Valley Civilisation lay in territory awarded to Pakistan, the Archaeological Survey of India, its area of authority reduced, carried out large numbers of surveys and excavations along the Ghaggar-Hakra system in India. Some speculated that the Ghaggar-Hakra system might yield more sites than the Indus river basin. According to archaeologist Ratnagar, many Ghaggar-Hakra sites in India and Indus Valley sites in Pakistan are actually those of local cultures; some sites display contact with Harappan civilisation, but only a few are fully developed Harappan ones. As of 1977, about 90% of the Indus script seals and inscribed objects discovered were found at sites in Pakistan along the Indus river, while other sites accounts only for the remaining 10%. By 2002, over 1,000 Mature Harappan cities and settlements had been reported, of which just under a hundred had been excavated, mainly in the general region of the Indus and Ghaggar-Hakra rivers and their tributaries; however, there are only five major urban sites: Harappa, Mohenjo-daro, Dholavira, Ganeriwala and Rakhigarhi. As of 2008, about 616 sites have been reported in India, whereas 406 sites have been reported in Pakistan.
  
  Unlike India, in which after 1947, the ASI attempted to "Indianise" archaeological work in keeping with the new nation's goals of national unity and historical continuity, in Pakistan the national imperative was the promotion of Islamic heritage, and consequently archaeological work on early sites was left to foreign archaeologists. After the partition, Mortimer Wheeler, the Director of ASI from 1944, oversaw the establishment of archaeological institutions in Pakistan, later joining a UNESCO effort tasked to conserve the site at Mohenjo-daro. Other international efforts at Mohenjo-daro and Harappa have included the German Aachen Research Project Mohenjo-daro, the Italian Mission to Mohenjo-daro, and the US Harappa Archaeological Research Project (HARP) founded by George F. Dales. Following a chance flash flood which exposed a portion of an archaeological site at the foot of the Bolan Pass in Balochistan, excavations were carried out in Mehrgarh by French archaeologist Jean-François Jarrige and his team in the early 1970s.
