You might want to consider Chemical Engineering too if you have an interest in chemistry but are looking for something a bit more practical.
I have seen published tables in newspapers and magazines which say that Chemical Engineering has the highest average wages out of all the engineering disciplines but i have no idea what the employment prospects are like in that field for new graduates.
Alot of accountancy and finance companies have been actively recruiting science and engineering graduates recently too for their numeracy skills.
Based on my own experiences i would echo Ham-Phisted's earlier remarks. Find a course you will enjoy because any of the science based degree courses can be a tough slog and if you want to do well you will have to put in alot of hours. Concentrate on finding a course you will enjoy and excel at rather than worrying about the scope for employment.
