Who actually picks Assam is on the record: labourers shipped in under contract from central India, from the 1860s on. Less on the record is that the government tried something else first: it taxed its own peasants' opium to force them onto the gardens instead. The tax did not produce a workforce. It helped produce a revolt. The Authority certifies the failure along with the fact, because the strength in your cup was decided partly by both.

A labour problem with no labour in it, by the 1850s

The Company had its valley, its plant, and its first sold chests by 1839. What it did not have, as gardens spread through the 1840s and 1850s, was enough hands to pluck and process any of it at scale. The obvious answer was the people already standing in the valley. Assamese peasants held land, grew their own rice, and had no obvious reason to sign on for garden wages set by the planters who wanted them. Officials did not read that as a rational choice. They read it as a character flaw, and the flaw they had already settled on, years before any tax existed to prove it, was opium.

The case was on the record by 1858, and the tax followed in the early 1860s

As early as September 1858, one colonial clergyman, the Reverend Mr. Higgs, set the reasoning down for his superiors in terms that left nothing to read between: state-distributed opium, he wrote, "is only supplying the place of the indigenous drug, and by forcing the lazy natives to work to gain the money to pay for it, it tends more than anything to bring Assam under cultivation" (Sharma, Modern Asian Studies, 2009, citing Home Political Proceedings, National Archives of India). The word "lazy" is doing real work in that sentence. It is not a stray insult. It is the premise the whole policy was built on: peasants were not choosing rice-farming over garden wages, they were defective, and a manufactured addiction bill would fix that.

The policy Higgs was defending took its final shape a few years later. In the early 1860s the colonial government banned Assam's own long-standing local opium cultivation outright and replaced it with a state monopoly, abkari opium, sold at a price the government set and raised for the rest of the century, from fourteen rupees in 1860 to twenty-six in 1879 and thirty-seven in 1890, nearly tripling (Sharma, Empire's Garden, 2011, reviewed in Down To Earth). A cash tax on a habit peasants already had would force them to earn wages to pay it, and tea gardens were the wages on offer.

What the tax actually bought, and the revolt it helped set off

The tax did not buy a workforce. The peasantry Higgs described did not report to the gardens in the numbers planters needed, and the "lazy native" verdict hardened rather than lifted. What it bought, reliably, was revenue and anger. In October 1861, peasants in Phulaguri, in Nagaon district, rose up against the new opium ban and the land and produce taxes stacked alongside it: a spontaneous uprising with no central leadership, in which a British assistant commissioner and soldiers of his party were killed, followed by mass reprisals ("১৬০ বছৰ ঐতিহাসিক ফুলগুৰি ধেৱাৰ," Dainandin Barta). The government had every reason to keep collecting a tax that produced revenue and none to see it succeed at the job it was sold on.

The workforce that came from far away instead

Local hands still had to come from somewhere, and the valley itself was tried once more before the government looked outside it: Kachari cultivators from Lower Assam were recruited next, and, Sharma records, "gave satisfaction, for a brief while," before also proving unwilling to stay. Only then did planters reach past the valley entirely, to labourers recruited under indenture from the Chota Nagpur plateau and the Central Provinces, some 1,500 kilometres (about 930 miles) away by road, contracts a worker could be jailed for breaking, as the Authority has certified elsewhere. The same officials who had just called Assamese peasants unfit for garden work now needed the newcomers described in the opposite terms: hard-working, compliant, suited to exactly the labour the locals had supposedly refused. The tea-tribe communities descended from that recruitment still live in the valley today, generations on from a policy aimed at somebody else.

The verdict that outlived the tax

A tax built to manufacture a workforce produced a revolt and a revenue line instead, and the character verdict it was supposed to justify was never withdrawn when the tax failed to bear it out. It was simply carried forward and pointed at a different population, one with no say in being recruited or in the label attached to it. Assam's tea got its workforce in the end. Whether the cup in your hand takes milk or not, it was topped up, at the start, by a tax that missed and a verdict that did not.
