Rev. Mr. GUICHARD, the financial agent of the Pittsburg Presbyterian Hospital, was in town last Saturday. His Hospital has been the recipient of many gifts from people of this place, notably from Miss Maggie MCDONALD, and Mr. GUICHARD hopes to induce McDonald to endow a bed at the Hospital. This will take $7,000. It is probable that some of our rich Presbyterians who are hunting an investment which shall bring them in returns after they shall have ceased to need their six percent, mortgages and bonds--it is likely that these will find no better place for their money than his Hospital. It is a pity we have to have denominational institutions of any kind; but the establishment of a hospital is always a good work.
