[9] Spon[10] was also an international author of civil engineering books, such as Workshop Receipts[11] and The Present Practice of Sinking and Boring Wells.

[13] Spon was interred at St John the Evangelist Church in High Cross village in 1890.

[15] SPC manufactured various high explosive powders for use in torpedoes, artillery shells, small arms ammunition (for the military and sporting) and mine blasting.

SPC won the litigation because their chief chemist demonstrated that their nitro compound differed to that of Dynamite Nobel's.

[34] Their 1900 catalogue lists all their products, along with extensive reviews on their powders' performances in The Field magazine.

[35] The company employed two of the U.K.'s pioneering ballistics experts: Frederick William Jones OBE and R W S Griffith.

[36] The company continued to produce high explosive powders until it ceased trading circa 1910 and was dissolved by 31 December 1916.

[41] Their product was extensively used in the First World War, especially in mortar warheads[42] and Mills bombs (hand grenades).

[43] William Herbert McCandlish the director of the Sabulite Works patented a new hand grenade for use in the Great War[44] and a new cutting machine for cordite.

A former employee of the Sabulite company, Harry Sears,[46] purchased the 33-acre factory site in circa 1946.

He was formerly employed in the same role at the Cotton Powder Company in Faversham,[47] until that site was shut down after an explosion on 2 April 1916[48] Sears utilised the existing factory buildings to open the Sabulite Snap Company,[49] which produced snaps for Christmas crackers.

[50] To the west of Round Wood in a grass meadow are the remains of three brick drying houses.

From the bridge there, on the right-hand side of the bank, lies one of the millstones used in the grinding process for the smokeless powder.

[51] The Douglas fir trees that briefly line Barwick Lane were planted for Mr J.D.

[52] The fields that run between the river Rib and residencies were used as a range, storage, testing/experimental work and disposal during SPC's and Sabulite's tenures.

A small quality of original boxes, cans and munitions were shown in an article written by Will Adye-White.

There are no bus service, shops, telephone boxes, post offices or churches in Barwick.
