Mosquitoes, house-flies and roaches will have been practically exterminated.
Strawberries as Large as Apples will be eaten by our great-great-grandchildren for their Christmas dinners a hundred years hence.
There will be No C, X or Q in our every-day alphabet. They will be abandoned because unnecessary.
There will be no wild animals except in menageries.
Ready-cooked meals will be bought from establishments similar to our bakeries of today.Any that you find particularly interesting? Be sure to explain why.
