Crude map of Elk Lake region, drawn by Julius Chambers. He called the lake "Lake Dolly Varden", a Dickensian name he also gave to the canoe he used on the trip.
While on sick leave on June 4, 1872, he discovered Elk Lake, adjoining Lake Itasca, in the Lake District of Northwestern Minnesota and declared it to be the source of the Mississippi River.[Note 2] For this he was made a Fellow of the Royal Geographical Society. This led to a series of newspaper articles and the book The Mississippi River and Its Wonderful Valley (1910).[Note 3]
Julius Chambers in 1872
Later in 1872, he returned to work and undertook a journalistic investigation of Bloomingdale Asylum, having himself committed with the help of some of his friends and the city editor. His intent was to obtain information about alleged abuse of inmates. After ten days, his collaborators on the project had him released. When articles and accounts of the experience were published in the Tribune, it led to the release of twelve patients who were not mentally ill, a reorganization of the staff and administration of the institution and, eventually, to a change in the lunacy laws.[Note 4] This later led to the publication of the book A Mad World and Its People (1876). From this time onward, Chambers was frequently invited to speak on the rights of the mentally ill and the need for proper facilities for their accommodation, care and treatment.
New York Herald
In 1873, he joined the staff of the New York Herald and was foreign correspondent for the newspaper for fifteen years. In 1887, his editor-in-chief sent him to Paris to launch the Paris Herald.
In 1890, Pulitzer, Chambers, et al. were indicted for posthumous criminal libel against Alexander T. Stewart for accusing him of "a dark and secret crime", as the man who "invited guests to meet his mistresses at his table", and as "a pirate of the dry goods ocean." The charges were dismissed by the court. This sort of criminal action was common at the time and both Pulitzer and Chambers were indicted in a number of cases, in some of which they were acquitted, in others convicted.
Chambers also wrote a column for the Brooklyn Daily Eagle, from 1904 onwards, called "Walks and Talks" and he continued to write it for the rest of his life.
He continued his travel writing and lectured in journalism at Cornell University from 1903 to 1904, and at New York University in 1910.
In addition to his works of fiction, he published over a hundred short stories and had two plays produced in New York, both comedies.
Chambers was married twice. For years he was a member of the Lotos Club, New York.

^There is disparity about an unused first name. The Americana Vol.4 (1911) calls him Charles Julius Chambers,Dictionary of American Biography (1936) and The Delta Kappa Epsilon Quarterly (1893)  call him James Julius Chambers. Regardless of the correct name, he used neither one in practice, nor an initial in its place.
^Other white men (William Morrison 1803, Schoolcraft 1832, and Nicollet 1836) had been there before him, but had said nothing about it as, at the time, it was part of Lake Itasca, subsequently separated by natural causes, it is believed. (See reference "The Glazier Fiasco")
^The following notice appeared in the Brooklyn Daily Eagle on July 17, 1872,
"Julius Chambers, who undertook to paddle his canoe Dolly Varden from Lake Itaska to New Orleans, reached Quincy, Illinois, yesterday and shipped his canoe to St. Louis on the steamer Rob Roy."
^The following notice appeared in the Brooklyn Daily Eagle on November 30, 1877,
"The lady whose suit against the Bloomingdale Asylum was mentioned in the Eagle on Wednesday is Mrs. James O. Norton. Mrs. Norton has been indefatigable for the past year to have her experiences of asylum life made known to the public, with a view toward ameliorating the condition of those suffering in them, and has decided that the course she has pursued is the best. She has put her case in the hands of Mr. John D. Townsend, of New York, whose name is associated with the exposures made several years ago by Julius Chambers, and he doubtless will secure a legal victory for this worthy lady"
