midnight
I am putting up some compounds in which I really have faith . Of course they have got to await their time to be tested , but I believe in them . I have grown stuff so carefully , gathered it according to rules , washed it decently , and dried and mixed it with such scrupulous care . Night after night I 've sat over the books until midnight and later , studying combinations ; and day after day I 've stood in the laboratory testing and trying , and two or three will prove effective , or I 've a disappointment coming . '' `` You have n't wasted time ! I 'd much rather take medicines you make than any at the pharmacies . Several times I 've thought I 'd ask you if you would n't give me some of yours .
