The wooden objects are keg taps or spigots. The one in the foreground was made by John Sommers. Below is one of their advertisements from 1908, plus, just for fun, the masthead of the magazine it came out of.
First up The Glen. Based on old maps and the story told by the Maiers, I think this is a reference to the Hurlbut farm (sometimes spelled Hurlburt), pictured below in a photo I stole from Google. The book Albany Chronicles describes it as "the country-seat at Glenmont, upon the eminence west of "The Abbey."
Mr. G. D. W Hurlbut is Gansevoort DeWandlaer Hurlbut (1857-1901) son of Elisha Hurlbut (noted NY Supreme Court justice) and Catherine C. VanVechten Hurlbut.
The other property in the story is The Mont or The Mount. I believe this is the Patterson farm located up the hill from Anders Road off of a long driveway on the right. Conveniently, this property at 111 Glenmont Road is for sale if you would like to spy it out. Top picture is from Zillow. The bottom one shows the house back in the day and is courtesy of the Bethlehem Historical Association.
BHA records indicate that this is the Patterson house, Glenmont Hill which matches up with the old maps of the area. The town's OARS system says the house was built in 1901, which lines up with the tenancy of John J. Patterson. A search of the Altamont Enterprise did not turn up any info regarding a property called The Mount. I did turn up the tragic story of John Patterson (John J.'s father) and his nephew James Patterson. Both were killed in September 1898 in an accidental explosion at their stone quarry.
So, I very much like the story of The Glen and The Mont, but so far have not found any primary sources to back it up. For now, I'll call it plausible but not proven.
And a final note...wonderfully, the 1880 US census has the Frazers, Hurlbuts and Pattersons all on the same page.
Dwelling house 285 is the Fraziers (John and Ann and their daughters Jane, Kate, Mary, Sarah & Elizabeth.)
Dwelling house 286 is the Pattersons (head of household John and his son John J. daughter Louisa Rockefeller and her husband BR, nephew James Patterson, plus 4 other single adult men.)
Dwelling house 293 is the Hurlbuts ( E.P. and wife Catherine, sons Gansevoort and Ernest, plus George Pattendon farm laborer, Catherine Cahill and Elizabeth Callahan domestic servants and Elizabeth Callahn, cook.)
