Recently we noted the singular ignorance of popular magazine writers about things in botany and horticulture, that they could know all about by a few moments of investigation, if they were not so impressed with the idea that they knew all that is worth knowing. The case then was Bret Harte. Before us we have another case in Ruskin, the teacher on Art. He started to write a book on botany, showing how it should be taught, and how miserably it was pursued by botanists, when, by his own confession, he did not know what a moss is. But he quarrels with everything that botanists have done and would reorganize the whole thing. In nomenclature he would change all the terms in use. In the place of ovary he would have "treasury," pistil he would replace by "pillar," and for the stigma he would have "the volute." Just how much the study of botany would be helped by these changes it is hard to see, but the case exhibits the sort of stuff that passes for literary smartness.
