Show scientific miscellany electric horticulture prof S lemstrom assures us is now practicable although althou gih not fully understood in his experiments of lost last year the application of the electric electr le current increased the yield of seeds at least forty per cerat and of roots from twenty five to severity five per cent the results varying with the kind of plant and the nature of the soil the production off of strawberries rasp raspberries berries was raised as much as seventy five per cent while the time of ripening rl was shortened one third it was proven among other things that electricity might damage plants on elea clear hot hays in the aib absence sence of abundance of water prof te lemstrom m is uncertain whether his electrification ficat fi jion of the dr air

suppressing the coolie traffic from the infected provinces the presence of a considerable quantity of liquid carbonic oar bonic acid in the rocks is among the surprising revelations of the microscope
