FORE:��I don��t know,�� Jeff spoke dubiously, uncertainly. ��We��ve gone over all the things we can think of that might go wrong��but������

FORE:They reached the kitchen window and looked out. There was a figure there, and what looked like another one in the background. A lantern stood on the flags; the first figure pitched something on the ground that looked like a coil of rope.

Hexane distillation systems, tall oil distillation systems, benzene distillation systems, lubricating oil refinement systems, xylene-free distillation systems, low-boiling gas distillation systems, ethylbenzene recovery systems, fusel oil distillation systems, naphthalene distillation systems, propylene recovery systems, and turpentine oil distillation systems.

FORE:It may be noticed that the carriages of some lathes move on what are termed V tracks which project above the top of lathe frames, and that in other lathes the carriages slide on top of the frames with a flat bearing. As these two plans of mounting lathe carriages have led to considerable discussion on the part of engineers, and as its consideration may suggest a plan of analysing other problems of a similar nature, I will notice some of the conditions existing in the two cases, calling the different arrangements by the names of flat shears and track shears.Prout nodded. All this was no news to him. Lalage paced up and down the cell fiercely. His eyes were full of sullen fire.
