The remainder are optional to Juniors and Seniors. Systematic botany consists entirely of laboratory and field work. In addition to the above courses a course in bacteriology is offered the first half of the second term. Herbarium work is also given, in which instruction is given in collecting, mounting and classifying plants. During the past year the following have been added to the material equipment of the department: A warming box for keeping microscope and object being examined at a uniform temperatnre—this box is used principally in physiological botany; a dissecting
phases, petrography, or the modern methods of investigating rocks, and the different branches of mineralogy and crystallography. This is accomplished by lectures and laboratory instruction principally, although students are constantly advised to provide themselves with the best books on the various subjects. The work in general geology is begun in the fall term, and a ten-weeks' course is offered as an optional study for all students in the University above the Sophomore year. This is followed in the spring term by a ten-weeks' course in economic geology open to all students

microscope for use in histological botany; a hand microtome for use in general botanical work; a camera lucida for general botanical work; five compound microscopes for general botanical work; an electro-motor for physiological botany; an auxanometer for physiological botany, and a number of objectives, eye pieces and photograph lens for general work.
DEPARTMENT OF PHYSICAL GEOLOGY AND MINERALOGY.
This department gives instruction in the various branches of physical geology, including economic geology, dynamic geology in all its
who have had the beginning geology or its equivalent.
In mineralogy the work is begun in the fall term and may be continued uninterruptedly for thirty weeks. In addition to this a ten-weeks' course in petrography proper is offered the first half of the spring term for those who have taken mineralogy during the fall term.
For those who wish to become specialists, graduate work is offered both in physical geology and mineralogy to a sufficient extent to occupy two or three years.
In connection with both the under-graduate and graduate studies a course in field geology
