Yet, there are not wanting evidences that the two groups were quite distinct and that the Germans, as a foreign group, were sensitively class conscious. This is shown, for example, by the race appeals in their business advertisements. To call attention to one’s nationality when offering services of a personal nature, like those of the physician, or the dentist, or even the druggist, is reasonable and correct. But there is no good ground for assuming that nationality makes a difference to the purchaser of lime. Why then the advertisement of a _Deutsche Kalk Haus_ (German lime house), unless there was a feeling that the German dealer would be favored by German buyers simply because he was German? This is a typical example which goes to show the existence of a city within a city, a German Milwaukee which tended to live its own group life, for which, as already explained, it possessed, within itself, great facilities. Occasionally some relatively minor happening threw this feeling of separateness into strong relief, as when, in 1850, a German scholar published in the Milwaukee papers of his language the story of his relations with the chancellor and board of regents of the University. He thought they had promised him a chair, but afterwards they made it plain that no contract had been closed with him. He may or may not have had cause of complaint. But what he professed to do was to lay the whole matter before the Germans of Wisconsin, in order that they might know how the board of regents “flouts the wishes of the German citizens,” how it keeps its promises “to Germans,” and how little it regards the rules of ordinary courtesy “in dealing with Germans.”[57] No doubt the design was to bring political pressure to bear on the regents, but the device would not have been resorted to had not the recognized racial unity among the Germans rendered that a hopeful plan.
