I mentioned previously that I've been reading a lot of old farming books. This past weekend I came across an example of "old texts gone bad", as I like to say. These are instances where clearly the author's day and age got the better of his beliefs. I always wonder what madness we believe in today that will be ridiculed in the future, but for now I'll just do my best to avoid the madness of years gone by.
In this particular instance I was reading "The Cow: Dairy Husbandry and Cattle Breeding" by M.M. Milburn. The book was printed in 1852 and is available for free courtesy of Open Library or Google Books online. There's lots of old texts available for free on the internet, you just have to track them down. Usually, they're more helpful than more recently published books. However, Milburn went off on a tangent about 50 pages in that really makes me wonder just how much of his other information I should trust.
It starts when he writes "Some very grave facts have been arranged and classified to show that when a pure-bred animal has once been impregnated by one of another, such impreganted animal is thereby for ever afterwards a cross, and may be expected to produce a cross-bred, and no more pure-bred young."
