Sorry, but it's all too pat:

"1879 - The oldest sweet tea recipe (ice tea) in print comes from a community cookbook called Housekeeping in Old Virginia, by Marion Cabell Tyree, published in 1879:

    Ice Tea. - After scalding the teapot, put into it one quart of boiling water and two teaspoonfuls green tea. If wanted for supper, do this at breakfast. At dinner time, strain, without stirring, through a tea strainer into a pitcher. Let it stand till tea time and pour into decanters, leaving the sediment in the bottom of the pitcher. Fill the goblets with ice, put two teaspoonfuls granulated sugar in each, and pour the tea over the ice and sugar. A squeeze of lemon will make this delicious and healthful, as it will correct the astringent tendency.

1884 - This may be the first printed recipe using black tea, which has become so universal today, and could also be the earliest version of pre-sweetened iced tea, the usual way of making it in the South today. Mrs. D. A. (Mary) Lincoln, director of the Boston Cooking School, published Mrs. Lincoln's Boston Cook Book: What to Do and What Not to Do in Cooking in 1884. On page 112, there it is: iced tea, proving that the drink was not just a Southern thing.

    Ice Tea or Russian Tea - Make the tea by the first receipt, strain it from the grounds, and keep it cool. When ready to serve, put two cubes of block sugar in a glass, half fill with broken ice, add a slice of lemon, and fill the glass with cold tea."

I don't have historical statistics handy, but an Internet search turns up the facts that California's population in 1900 was 1,485,053, and in 1910 2,377,540. If the growth was smooth (and I'm sure that it wasn't), that would mean that in 1903 California had a population of 1,752,803 (rounding off the average annual growth of 89,249.6 to 89,250 and doing away with that pesky 6/10th of a person). (This data from the US Decennial Censuses for 1900 and 1910.)

As a librarian, I suspect ALL statistics that don't give their source.
It takes some joy out of life, but satisfies my idea of Truth.
