About May 10 the ramparts, which were constructed of palisades and earth, were completed. Guns were taken from the _Kalmar Nyckel_ and mounted on the walls; the Swedish banner was raised on the flag-pole, and “with the report of cannon the fort was named Christina.” Two houses were erected inside the palisades, one of which was probably used for a dwelling house, the other for a magazine or store house. They were built of unhewn logs, and the dwelling house had loopholes and probably two or more little windows. The roof was gabled and most likely covered with small timbers split in two. In the corner of the dwelling a fireplace was made of bricks brought over on the ships. Rough benches, chairs and tables were constructed from split timber, and it is likely that beds of some sort were made. The Swedes came in contact with the Dutch shortly after their arrival. In the beginning of April Minuit sent his sloop up the river to examine the position and strength of the Hollanders, and to establish relations with the Indians north of the Schuylkill. The sloop sailed above Fort Nassau unobserved, but on its way back to Christina it was discovered by the greatly surprised Dutch commander, who at once set about to ascertain the identity and business of the new-comers. Shortly afterwards Minuit himself attempted to pass the Dutch stronghold; but the garrison was now on the alert and “Peter May sailed down” to meet him. May demanded to know the reasons for his presence in the river, and wished to see his commission, warning him not to pass the fort. Minuit refused to exhibit his papers, “saying that his Queen had as much right there as the company”, and desired to proceed on his journey. He was compelled to return to his camp, however, and he probably made no further attempts to go above Fort Nassau. Peter May reported the occurrence to Governor Kieft and, when Jan Jansen, who had been absent at New Amsterdam for some time arrived at the South River about the middle of April, he immediately protested in writing against the Swedish occupation. Minuit replied to the protest, styling himself “Commander in the service of Her Royal Majesty of Sweden”, and paid no heed to Jansen’s warnings. When Governor Kieft was informed that the words of his commissary had no effect, he drew up a protest himself “against the landing and settling of the Swedes on the Delaware.” He reminded “Peter Minuit that the whole South River of New Netherland had been many years in their possession and secured by them above and below by forts and sealed with their blood”, and informed him that the Dutch would not suffer him to intrude between their forts and that “the blame for all future mishaps, damages, losses, disturbances and bloodshed”, which might arise as a consequence of his actions, would fall upon him. The protest was read before Minuit, but he made no reply to it, and continued his work as before. [Illustration:
