in Ancoats, Manchester
Maps of the late 18th century apply the name 'New Islington' to a small plot of land in Ancoats, while on 19th century maps the name is given to a specific road in the same place, which ran east/south east from Union Street to Canal Street.
The 1848 O.S. map identifies a mill as New Islington Mill. The remains of this mill were demolished in the 1970s, and in recent years it has been the subject of much attention, including archaeological excavation. However, the picture is somewhat clouded by uncertainties about the early history, and by the fact that there were other mills in the immediate area which were certainly 'New Islington mills'. In an effort to clarify matters, or not, the identified mills or factories will be designated as A, B, C and D. The letters do not imply chronological sequence.
This is the mill shown on the 1848 O.S. map, and whose buried remains were subject to much scrutiny, being regarded as an early example of a steam-powered cotton mill in Manchester.
A book published in 2007 gives an excellent account of the findings relating to New Islington Mill (and to the nearby Waller's Mill and Salvin's factory), and traces the history of the area and its industries 
The investigation was also featured in a 2008 book , which puts the mill in the broader context of Manchester industrial and social history. The mill was described as one of eleven or more cotton mills which had been built in Manchester by 1788.
Perhaps the most interesting finding discussed in these two sources is clear evidence of a waterwheel, and the conclusion that this would have been served with water by a Savery-type pump of the type made by Joshua Wrigley. Such engines would have been cheap to buy, but expensive to run, being very inefficient.
In preparing this entry for Grace's Guide, additional information has been identified which broadens and complicates the picture somewhat.
A map in Lewis's Manchester Directory for 1788 clearly shows a building straddling Shooter's Brook at New Islington. The brook evidently passed through the building, about half way along its length, and there can be little doubt that this was a mill of some description. Surprisingly, there is no evidence of a dam or reservoir upstream, but this apparent lack also applied to Salvin's cotton works downstream. No scale is given on the map, but by comparison with other features on the map, the length is estimated at about 100 ft, and the width slightly less than 20 ft. The building was L-shaped, although the short leg only projected about 10-15 ft. A track passed immediately to the north of the mill, heading across fields to Bradford Road. The alignment of the mill and the track are such as to cross the brook at right angles. The cotton mill shown on later maps (Mill A) is aligned at a slightly different angle to the '1788' mill, suggesting that it was not developed from the 1788 mill. This presupposes that the 1788 drawing is an accurate representation. It should be noted that this mill is completely absent from Green's 1787-1794 map and from Laurent's 1793 map. However, these maps do show an L-shaped building straddling Shooter's Brook further downstream, close to Salvin's Mill. Therefore, either Lewis's map is wrong, or the '1788' mill was demolished before the other maps were drawn.
In either case, it follows that this 1788 mill, 'Mill B', is not related to the 'New Islington Mill' (Mill A) which was the subject of archaeological investigation.

This will be designated 'Mill C'. It is probably the same as that advertised for sale in 1794.
Green's map of 1787-1794 shows no buildings at the site of the '1849' New Islington Mill (Mill A). However, there is a group of buildings shown immediately to the west of that site, at the junction of Union Street and a short un-named street (which became New Islington). The name New Islington appear alongside this block of buildings. This group includes a fairly large house, a garden, ten buildings (almost certainly houses) with extensions at the back, several other connected properties, and a larger building. There is no obvious sign of a reservoir, but otherwise, this group is not inconsistent with the descriptions in the sale notices. In fact it is not obvious from the map how water would have been fed from Shooter's Brook, which appears to be at a lower level than the buildings.
Note: A group of buildings is also shown at this position on Lewis's 1788 map, although the scale is too small to show useful detail. However, a point of interest regarding water supply is the presence of a small, sinuous stream which approached the buildings more closely than did Shooter's Brook. In fact, Laurent's 1793 map shows two ponds immediately across Pott Street from the buildings.
If this is indeed 'Mill C', then an interesting aspect is the presence of garret workshops over the houses, containing mules, in a steam-powered mill, especially in view of the shape of the group, which formed three sides of a 'right trapezium'.
The statement in the 1797 advertisement Steam Engine, upon Messrs Boulton and Watt's Principles and Construction might imply that the engine was not actually made by B&W. If so, a likely candidate maker would be Bateman and Sherratt, who 'pirated' Boulton & Watt's design features.
Bancks's 1831 map shows that mill buildings had now been built at the location recently subjected to archaeological investigation (Mill A). They are identified as Johnson & Brooke's Cotton Mill. There is a small reservoir at the eastern (Shooter's Brook) end. The postulated industrial building and the larger house and garden in the 18th century maps are no longer present, but the houses in that block, on Union Street and New Islington, remain. Another cotton mill is shown on the opposite side of New Islington.
When was 'Mill A', as shown on the 1831 map, built? Ref. 2 refers to factory buildings shown on the site on Bancks and Thornton's map of 1800, and a Mosley Estate plan of 1805-8 also shows the buildings, together with a small pool adjacent to the mill, served by Shooter's Brook. A 'Pocket Plan of Manchester and Salford' published in 1800 shows no mill here, but, of course, it may not have been absolutely up to date when published. Aston's 'A Plan of Manchester and Salford' 1804 does show 'Mill A'.
The earliest identified plan showing the basic layout of Mill A dates from c.1822 . This shows the main building, running along New Islington, as two connected factories, both of 5 storeys. In addition, parallel and to the north of them, is a long narrow two storey 'Batting Shop' and a small stable. Connected to the NW corner of the main factory is a building marked as 'House', with another house projecting from the SW end, its end wall being next to the brook. Behind this house, and against the factory's end wall, is the engine house. In the angle between the engine house wall and the back of the house is a building marked 'Kitchen'.
Bancks's 1831 map shows another cotton mill (we shall call it 'Mill D') located at the junction of New Islington and Pott Street, directly across the street from 'Mill C'. Some excavation of the site was undertaken in 2004, and the findings and other information are discussed in Ref. 2, where it is referred to as Waller's Mill. A notable finding was the relative paucity of demolition material, implying careful dismantling, possibly for reuse of materials. This statement is significant in relation to information which has been found relating to an 1838 sale of building materials (see below).
The c.1822 plans referred to above include Waller's Mill (Mill D), identified as the factory of T. R. and S Waller. The longer part of this mill, designated as a Factory 'b', had 6 storeys and a loft, while the smaller western end had 4 storeys and was identified as a Factory 'a' and machine maker's shop.
'Sale by Auction. To Cotton Spinners and Manufacturers by Power.—Valuable Cotton Mills, Steam Engines, Warehouses, and Cottages, at New Islington, Ancoats, Manchester.—Exempt from Duty. By Mr. WINSTANLEY, by order of the assignees of Messrs. Welch and Sells, bankrupts, at the Blackfriars Inn, Blackfriars Bridge, in Manchester, on Tuesday the 4th day of September inst., twelve o'clock at noon precisely and subject to such conditions of sale as will be then and there produced:
'Lot 1. A PLOT of LAND, near Ancoats-lane, Manchester, bounded on the north by and extending three yards into Boond's-row, on the south by and extending four yards into Islington-street, on the east in an irregular line by Shooter's Brook, on the west by and extending two yards into Pott-street, and containing on the north 18 yards, on the south 80 yards, on the east in irregular line 48 yards, on the west 45 yards, and containing in the whole 3711 square yards of land; and also all those two Cotton Mills or Factories, with the engine-house, a steam engine of 20 horses power, by Boulton and Watt, already set up; and another of 16 horses power, partly set up; boilers, mill gearing, steam and gas pipes, warehouses, and other erections and buildings to the said cotton mills belonging, the whole of which were late in the possession of the said Messrs. Welch and Sells. — And also all those thirty-two Dwelling-houses, standing and being upon the said land, and fronting into Islington-street, Factory-yard, Boonds-row, and Pott-street aforesaid.—The land is freehold of inheritance, and is subject to the payment of small yearly chief rent of £43 13s. 1½ d., reserved by feoffment, dated the 30th August, 1798, and will be sold subject thereto, and to the powers for recovery thereof, and to the performance the several covenants, &c. therein contained.—The cotton mills are well and substantially built, each five stories high, and one with attic; one is 81 feet long and 48 wide, and the other 54 feet long and 30 feet wide; they are completely cellared under, are situated in a very populous and improving neighbourhood, and are well worth the attention of spinners, manufacturers, and capitalists.—The cottages produce an annual rental of £194 2s., and are in good repair. Two of the rooms in the small factory are let to a tenant, at the annual rent £201, and turning to another tenant for 25 looms, at a rent of £75. A very large portion of the mills are unoccupied, but may be immediately let to respectable tenants, at good rents, and the present tenants hold under such arrangements will enable the assignees to give possession shortly after the sale, if required.
'Lot 2. The INTEREST of the said assignees in LETTERS PATENT, dated the 5th day of October, 1834, granted to the said Thomas Welch, for his invention of a new method of taking up for Power and Hand-looms. This invention a very valuable improvement in the manufacture of light fabrics by power loom. The premises may viewed on applying at the Cotton Mills; and further particulars obtained by applying to Messrs. ATKINSON. BIRCH, and SAUNDERS, Solicitors, 3, Norfolk-street; or to Messrs. PEET and HOBSON, Accountants, St. James's-square, Manchester.'
This evidently refers to 'Mill A', based on the stated boundaries - Boonds Row, Pott Street, 'Islington Street', and Shooter's Brook. The 'feoffment date' suggests that the mill was established in 1798.
We know from the above that the main mill buildings had five storeys. However, we know from Goad's Plans and from a 1967 photograph that the buildings on the site were shorter than originally built, and that the building which survived at the S.E. corner only had two storeys plus a basement. Commenting on the 1967 photo, Ref 2 observes that it is impossible to ascertain whether this component of the building was a reduced element of the original structure. In fact information has now been found which indicates that the mill was demolished, and that this was done as early as 1838. The incentive for demolition has not been established. Perhaps it was not 'fireproof', and difficult to insure? The evidence for demolition is presented below:-
1838 Sale Notice 
'Building Materials, Steam Engine. Boilers, Shafting, Mill Gearing, Gas Meter, Pipes and Burners.

We cannot be sure that it was 'Mill A' that was demolished. We do know that 'Mill D' had been demolished by 1848 (see below), and Ref 2 considered that it had been carefully dismantled, possibly to re-use building materials. On the other hand, the 1838 advertisement for the sale of materials does appear to relate to 'Mill D', based on the statement that it had been occupied by Welch & Sells, who, we believe owned 'Mill A' (based on the 1836-1838 sale notices). Also, archaeological evidence, summarised in Ref. 2, found evidence of only one boiler at Mill D, whereas two were included in the 1838 sale of materials notice. Fothergill's map of 1844 shows 'Mill D' still there, but this map does not give the impression of a particularly reliable source.
The 1848 O.S. map identifies 'Mill A' as New Islington Mill, having two long buildings. Although it seems that the mill had been demolished in 1838 (see above), one half of the southern building of the two is very similar in plan shape to the 1831 mill, but the eastern end has been extended over the former reservoir. This begs the question of whether only part of the mill had been demolished in 1838. However, the sale notice included 160 yards of ridge tiles, which seems consistent with wholesale demolition.
In fact although there is an apparent resemblance to the western half of the southern building in 1831 and 1848, the shape of the building as a whole in 1831 suggests progressive enlargement, while the the building in 1848 appears more uniform and monolithic.
Additional support to the assumption of progressive enlargement is obtained by going further back in time, from an 1828 advertisement:-
'To be Let, on reasonable Terms, a small Entire FACTORY, with good Turning, five stories, seventeen by nine yards, late in the occupation of Messrs. Welch and Sells, at New Islington, Ancoats ; or three Rooms in the adjoining larger Factory, each twenty-seven by sixteen yards.— Inquire of JOHNSON and BROOKES, on the Premises.'
Although the 1831 map is not of the same quality as the O.S. map, a check by scaling suggests that the advertisement refers to western end of the main (southern) building. The advertisement also illustrates that the building was then owned by Johnson & Brookes, but rooms were let out for cotton production. This was a common arrangement, the expression 'good Turning' suggesting that the owners supplied the power for the machinery.
Regarding 'Mill C', the space vacated in the established block, referred to in the '1831' entry above, had been filled by Queen's Foundry by 1848.
'Mill D' has disappeared from the map. A 'Machine Manufactory' is now shown on what had been a yard and/or vacant land west of Mill D.
Adshead's 1851 Maps of Manchester, Map 15, shows New Islington Mill (Mill A) as Armstrong & Hirst’s cotton mill. The S.E. end wall was angled to suit the line of Shooter's Brook, which passed under this end of the building. As a result, the S.E. corner of the building was 'chamfered off', and the chamfer remained until demolition of the building. After passing under the end of the mill, Shooter's Brook remained culverted until it made a brief appearance at at the former Sandford & Green's cotton mill (being used as a fever ward in 1851). At the west end of the New Islington (street), at the angled junction with Union Street, was a smaller cotton mill, under the name J & J Armstrong (Mill D). The Queen's Foundry, at the junction of New Islington and Pott Street, was occupied by Adam Woodward.
