Three Days at Agra by Herbert Andrews Newell first published in 1919.

No matter how experienced a traveler he may be, the new arrival at a strange place invariably feels at a disadvantage. This is particularly the case if sight-seeing be his object. He does not know just where to begin, and is uncertain in what order to take the places of interest he has come so far to visit. Enquiries pursued on the spot do not always tend to facilitate matters. He is frequently annoyed by finding that he has to retrace his steps and so cover the same ground twice. This leads to vexatious waste of energy, time and cash. Nor is this all he has to suffer. The usual result of much sight-seeing is a severe fit of mental indigestion. Even under the most favourable conditions it is difficult to assimilate a host of hastily acquired impressions, and quite impossible if any confusion of ideas prevails.
