This chimney is approximately 1½ miles northeast from where Central Pasto Viejo was located, and maybe a similar distance to where Central Triunfo was most likely located.  It lies within the municipal boundary of Humacao, not too far south of the boundary with Naguabo.  It is not listed by José Ferreras Pagán as an operating sugar factory in his 1902 book Biografía de las Riquezas de Puerto Rico.  He does state though that at the time, a vast amount of the land in the municipality of Humacao was dedicated to the cultivation of other products. 

A resident of the area said this hacienda was once called Victoria.  It is understood it has also been referred to as Hacienda Mulas which is a possibility since there is a brook running south of the chimney about 1,200 feet distant, called Quebrada de las Mulas.  That being the case and not sure of its correct name, it is identified as Hacienda Victoria and/or Hacienda Mulas, however with reservation as the name has not been confirmed.  It is possible that throughout the years, the hacienda had more than one name as it was common for new owners to change prior names as it is also possible it has been identified as being located in Humacao as well as in Naguabo due to changes in municipal boundaries.

This chimney has been identified as that of the old Hacienda Australia which is not correct.  According to Ferreras Pagán, Hacienda Australia was established in 1881 by Matías Grós as Hacienda Carmen and acquired in 1892 by Indalecio López who annexed to it Hacienda Buena Vista which he operated on a long term lease.  It appears it was then when it was renamed Australia. Ferreras Pagán states that Hacienda Australia was located on the east side of the road to Yabucoa in Barrio Candelero Abajo, approximately 5 km from the town of Humacao.  Yabucoa is south of Humacao as is Barrio Candelero Abajo, while this chimney is about 7 km northeast of the town of Humacao.  Based on Ferreras Pagán description of the location of Hacienda Australia east of the road to Yabucoa in Barrio Candelero Abajo, Hacienda Australia would have been be located in the immediacies of the resort today known as Palmas del Mar.  Thus, it is not reasonable to believe this chimney belonged to Hacienda Australia.

Public records show that the current owner of the lands where the chimney is located is Roberto Mendoza who operates a dairy farm there.  The records show that he acquired the property from the Land Authority of Puerto Rico who in turn acquired it from Eastern Sugar Associates.  That being the case, it is safe to assume the trapiche to which this chimney belonged and its surrounding land was at one time acquired by and formed part of Central Pasto Viejo, organized in 1907, which was one of the five sugar mills owned by United Porto Rican Sugar Co. later Eastern Sugar Associates.

Reportedly, the indentation near the top of the chimney was caused by lighting.
