So, instead of an 'Inspector of Roads' he is better described as a Bostancı Haseki.
2° Hasekis. It is a corps of three hundred non-commissioned officers, usually taken from among the Bostancıs. They wear a red cloth uniform, a sabre (ghaddaré), and hold a stick in their hands. (Pl. 149 and 150.) Those who are admitted to the corps receive this baton from the colonel, in the presence of the troops; each of them must pay the chief a ducat, and sacrifice a sheep from his hand, in the barracks of the company, which is situated in the seraglio. Sixty Hasekis are part of the Sultan's cortege, and are considered, for this reason, as bodyguards. The Bostancı-Başı, their chief, frequently sends them on commission to the provinces.

For the 2nd figure, Tchohadar (Çuhadar) means 'wool cloth wearer', Sergeant would be Tchaouch (Çavuş) which can also mean Usher.
5° Tchavouschs, corps de six cent trente hommes, divisé en quinze compagnies, et commandé par le Tchavousch-Baschi. Il y en a toujours une compagnie de service au Palais, avec son capitaine (Beuluk-Baschi). Les Tchavouschs ouvrent la marche du Sultan dans les solennités publiques. (Pl. 155 et 156.)
5° Çavuşs, a corps of six hundred and thirty men, divided into fifteen companies, and commanded by the Çavuş-Başı. There is always a service company at the Palace, with its captain. The Çavuşs open the march of the Sultan in public solemnities.

13° The Baş-Çuhadar or First Valet of the chamber has under him forty valets (çuhadarlar) who belong to the three other chambers. They follow the Sultan, richly dressed and the belt adorned with a cutlass, a dagger, and a whip with long chains, all of silver; but those of the chief are of gold.
