representative to INTERBULL since its beginning in 1983 and serves on its board of directors."INTERBULL—The International Bull Evaluation Service—is like a consumer report that objectively rates bulls raised worldwide, based on an extensive list of important quality standards," says Agricultural Research Service geneticist Rex L.

Igor Berezhnoy, from Maastricht University, developed the system with colleagues Eric Postma and Jaap van den Herik.All archaeological sites are palimpsests, that is to say, the end result of a series of events, including cultural events (a house was built, a storage pit was dug, a field was planted, the house was abandoned or torn down) and natural events (a flood or volcanic eruption covered the site, the house burned down, organic materials decayed).When the archaeologist walks onto a site, evidence of all those events is there in some form.Information about every level that is excavated is recorded, including depth below surface and volume of soil excavated; artifacts recovered (which could include microscopic plant remains discovered in the laboratory); soil type, color and texture; and many other things as well.By identifying the contexts of a site, the archaeologist can assign Level 12 in excavation unit 36N-10E to the foundation trench, and Level 12 in excavation unit 36N-9E to the context within the basement.Harris matrices may be compiled in the field as the archaeologist is recording the stratigraphy in her field notes, or in the laboratory, working from notes, photos and maps.

This article is part of the guide to something or other, and part of the Dictionary of Archaeology The best source for information about the Harris Matrix is the Harris Matrix project website; a recent software program is available known as the Harris Matrix Composer which looks promising, although I have not tried it out so can't tell you how well it works.

INTERBULL combines national evaluations of nearly 90,000 recent bulls from six breeds of dairy cattle.

Its objectives are to improve milk yield and quality; improve resistance to diseases, like mastitis; and increase the value of dairy cows—all while protecting genetic diversity.

The Harris Matrix (or Harris-Winchester matrix) is a tool developed between 1969-1973 by Bermudian archaeologist Edward Cecil Harris to assist in the examination and interpretation of the stratigraphy of archaeological sites.
