On June 1, 1837, they arrived at Fort Snelling, near where the Minnesota joins the Mississippi. Here they remained until the beginning of September, living in a log-house, and learning the Dakota language with the help of a missionary who had been in the field for three years. From Fort Snelling they departed on September 5, 1837, for their destination Lac-qui-parle, travelling with two one-ox carts and a double wagon. On September 18 they arrived at the station to which they had been appointed, and received a hearty welcome from the two missionaries who had settled there some time before at the earnest request of a Lac-qui-parle trader. Lac-qui-parle was a small place, a mere collection of buffalo-skin tents, in which lived some 400 Red Indians. Mr. and Mrs. Riggs found a home in a log-house belonging to one of the other missionaries. Only one room could be spared them, and although it was but 10 feet wide and 18 feet long they made themselves comfortable. Mr. Riggs wrote as follows in his account of their work among the Sioux[[1]]: 'This room we made our home for five winters. There were some hardships about such close quarters, but, all in all, Mary and I never enjoyed five winters better than those spent in that upper room. There our first three children were born. There we worked in acquiring the language. There we received our Dakota visitors. There I wrote, and re-wrote, my ever-growing dictionary. And there, with what help I could obtain, I prepared for the printer the greater portion of the New Testament in the Dakota language. It was a consecrated room.'

When Mrs. Riggs and her husband took possession of their one-room home they had much difficulty in making it comfortable, as they had been unable to bring on their furniture and domestic utensils. One person, however, lent them a kettle, another provided them with a pan, and bit by bit they collected the most necessary articles.

In the East missionaries have never experienced a difficulty in obtaining servants, but in Dakota neither male nor female Sioux would enter the Riggs' service. Consequently Mrs. Riggs had to perform all the household duties. They bought a cow, but neither of them knew how to milk her. Both Mr. and Mrs. Rigg tried to perform the task, but not until the cow had experienced considerable discomfort did Mrs. Riggs become acquainted with the art. Washing clothes was a performance which filled the Sioux women with wonder, for they were in the habit of wearing their garments unwashed until they became too old to be worn any longer. Very soon they adopted the white woman's custom, and, becoming fond of standing over the washing-tub, they took to washing Mrs. Riggs' clothes as well as their own. For doing so they were, of course, paid.

The missionaries who had preceded the Riggs at Lac-qui-parle had not been very successful, if success be judged by the number of converts made. The native Church consisted of seven people, but before the Riggs had been there many months nine were added. Most of these were women, and it was they, and not the men, who assisted in the building of the first church at Lac-qui-parle.

When Mr. and Mrs. Riggs had worked for some time with success at Lac-qui-parle they removed to a new station—Traverse des Sioux. But four years later the news reached them that since their departure from Lac-qui-parle there had been a sad falling back into heathenism among the converts, and they hurried back to their old station. Backsliders were reclaimed, and the missionary work carried on with increased energy.

But the missionaries had much to contend with. The Indians were hard pressed for food, and occasionally shot the mission cattle. Grog shops had been opened in the neighbourhood, and many of the Sioux bought drink when they should have purchased provisions. Excited by the fire-water, the Indians were frequently riotous, and, although they never assaulted the missionaries, it was clear that they might massacre them. On one occasion Mrs. Riggs had a very unpleasant experience. While her husband was away, twenty-six Sioux warriors paraded in front of mission house and fired their guns in the air. Mrs. Riggs was naturally somewhat frightened, until she found that they were not bent on murder and scalping. They had been searching for some Chippewas, but, having failed to find them, they fired their guns for practice.

Mr. and Mrs. Riggs continued their work with but few interruptions until 1862, when the Sioux rising occurred. It began in this way. The Sioux had assembled at Yellow Medicine to receive their annual allowance from the Government official. While distributing the allowance the official announced that the Great Father (President Lincoln) was anxious to make them all very happy, and would therefore give them, very shortly, a bonus. The Indians, having recently suffered greatly from want of provisions, were delighted at the prospect of an additional grant, and waited in the vicinity of the agency for its arrival. When it arrived the Sioux found to their dismay that it was a paltry gift of $2.50 a man. Their disgust and anger were increased by the knowledge that during the time they had been waiting for this insignificant present they could have earned from $50 to $100 by hunting. Unintentionally, a Government servant added fuel to the fire, and the Sioux, maddened, began their terrible massacre of the scattered settlers.

The news of the rising was carried quickly to the Riggs by friendly Indians, who urged them to hurry away as quickly as possible to a place of safety. But the missionaries were not disposed to consider the rising serious. The seizure of their horses and cows, and various other unfriendly actions performed by the people among whom they had lived for many years, soon, however, convinced them that it would be wise to depart. So gathering together a few belongings the little band of missionaries, some carrying children, crept away by night to an island in the Minnesota River. But on the following day the friendly Indians sent word to them that they were not safe on the island, and urged further flight.

Acting on this advice, the Christians waded the river and started on a tramp to the Hawk River, and on the way met other settlers, hurrying like themselves, to escape from the infuriated Sioux. Joining forces they proceeded on their journey, the women and children riding in two open carts, and soon met a wounded man, whom they tenderly lifted into one of the wagons. He was the sole survivor of a band of settlers which had been attacked by the Sioux.

Keeping a sharp look-out for the Indians, the fugitives continued their journey across the prairie. On the second night the rain fell heavily, and as the women and children could obtain no shelter in the open carts they crept under them. Wet and shivering, the fugitives found, when daylight came, that they had scarcely any food. Wood was collected, a fire built, and one of the animals killed and roasted.
