The recent passage of an act by the Rhode Island Legislature, making ten hours a legal day's work, is creating considerable disturbance among the manufacturing villages of that State. Upon the day on which the law went into operation many of the factories were closed the proprietors not being willing to have the law obeyed. A convention of manufacturers has since been held at Providence, and it was decided by them that the operatives should bargain to labor nine hours on Saturdays, and twelve hours during the other working days of the week, or they should not give them employment. Prof. Silliman, Sen., has resigned his situation in Yale College. His son has been appointed to succeed him. Prof. Silliman has long been a distinguished teacher and writer on scientific subjects. In chemistry he has long held a high place.
