Fred and Eliza Cabot are found in Jupiter, Dade County, Florida in about 1893 when Fred purchased the northern end of the Lydia Moss property, which is the old Ziegler property on Alt. A1A, southeast of the first railroad depot. The land around the railroad station in Jupiter had a huge shell mound. Fred thought this would be a good investment and removed all of it to build roads in St. Augustine and Palm Beach. The many men employed for the road building made it necessary to operate two commissaries, one which was managed by Paul Parker, and the construction gang managed by Fred Cabot. He received the contract to shell some of the principle streets in Palm Beach according to the July 14, 1894 issue of the Gazetteer.

In 1894 Fred also had the contract for supplying ties for the new FEC Railroad. His camp was about two miles below the Loxahatchee River located in the flat pine woods. The November 4, 1894 issue of The Gazetteer announced that F. M. Cabot was to build a hotel in Jupiter. He built a commodious house (hotel) called "The Cabot House" just west of the Jupiter Station in 1894. It burned in 1903 and an oleander was all that marked the spot well up into the 1900's. In April of 1895, Fred got the contract for filling in the low ground in the rear of the Royal Poinciana. Fred was also a member of The Jupiter Lifesaving Station Crew about 1895.

Fred ran an advertisement in the "1896 Directory, Guide and History of Dade County Florida" as F. M. Cabot, "General Contractor for all kinds of Grading, Clearing, Road Building, Street Grading, etc., P. O. Address, Jupiter, Florida." Under Leading Business Firms in the same directory, he is listed as "General Contractor, Jupiter, is well known in South Florida, both personally and through his business. He did the shelling of the street's here, and now has the contract for cutting through the first part of the unfinished portion of the canal, at the north end of Lake Worth, and also has the contract from the government for re-opening the River Inlet at Jupiter which, through the action of the tides, has during the past three years been completely closed. Both of these contracts will be completed before January, 1897."

In December of 1896 Fred was killed in a railroad accident near his home. He was first interred on the Cabot homestead on the south side of the Loxahatchee River, under the old live oak tree, located next to the small building which later became the old Zeigler home and school. The property was developed into Sawfish Bay Park by the Town of Jupiter.

His son, Fred Cabot III had his body transferred to Jupiter Cemetery in 1908. His was one of the first three burials at the "new" Jupiter Cemetery, now Riverside Memorial Park.
