In the 1820s surveyors of the interior of the New South Wales colony were required to select, survey and map out one mile square areas of land which were to be reserved for future villages as population numbers increased.

This remained empty through the 1830s, although it was surrounded by three substantial land grants to Simeon Lord and Joseph Moulder (to the north, south and east of the reserve), and to the west to William Ealy Sampson.

George Mills opened the Boree Inn about 100 metres (330 ft) to the west of Campdale's southwest corner on the main road boundary of Sampson's grant.

[3][1] By the 1850s Campdale had already been subdivided and continually leased, with a major part of the property being sold to the Flanagan family with Michael's daughters Emily, Henrietta and Margaret each owning a share.

During the 1860s it developed into a significant commercial centre including three flour mills, a foundry, three banks, 14 hotels and a daily coach mail service along the Great Western Highway.

Included in the design was a family chapel and substantial central staircase into which Dalton had built the stained glass window which commemorated his investiture as a Papal Knight in recognition of his services to the Catholic Church.

To overcome the problems associated with flooding on the farm, the Daltons had constructed a drainage system of rubble drains in the paddock on the Woodward Street boundary.

An editorial in the Bathurst Times of 14 April 1890 noted that Patterson had "by dint of hard work and exercise of skill, brought Cook Park, Orange to its present state of perfection".

[9] In 1900 and 1901 Patterson was seconded by the Government of New South Wales to organise the floral displays for the Federation celebrations in Centennial Park, Sydney and the arrival of the Duke and Duchess of York (the future King & Queen).

A club was formed in 1901 and the first official golf course, with sand greens, was created in the area of Bletchington, called Clover Hill, directly north of the town up to Kearney's Drive.

Most of this area was sub-dividable and the club moved south east in 1919 to 32 hectares (80 acres) outside the town on the Icely Road, opposite the present Canobolas High School.

On the one hand, the land was saved from subdivision, most of the Dalton's exotic trees planted in the 1880s and 1890s were preserved and the superb house, along with its large stables and its original Woodward Street lodge and gateway, was maintained in remarkably intact condition.

An area of 16 hectares (40 acres) on the Cargo Road side was divided into 20-metre (66 ft) building blocks and sold to provide revenue for repayment of the club's bank loan.

In 1919 the club moved from Clover Hill to a new site at Icely Road opposite the present Canobolas Rural Technology High School, setting up a 12-hole golf course on 32 hectares (80 acres).

[1] In 1949 the club engaged landscape architect Ilmar Berzins to undertake a master plan of the course, setting out the existing tree species and specifying future plantings.

'Glauca'), claret ash (Fraxinus oxycarpa 'Raywood'), Prunus spp., Japanese maples (Acer palmatum), copper beech (Fagus sylvatica 'Purpurea') and golden elms (Ulmus x hollandica 'Louis van Houttei') strategically sited.

The Himalayan cedars (C.deodara) marking the border with Orange High School in the south were planted in 1966 by Miss Edith Robinson and the clumps of flowering cherries were given in 1974-5 by Neville Hawke.

'Glauca'), claret ash (Fraxinus oxycarpa 'Raywood') Japanese maples (Acer palmatum), copper beech (Fagus sylvatica 'Purpurea') and golden elms (Ulmus x hollandica 'Louis van Houttei').

Other plantings north of the mansion include: tree tulip (Magnolia soulangeana), grape holly (Mahonia lomariifolia), Photinia glabra, Bhutan cypresses, silver birches (Betula pendula), ashes, copper beech (Fagus sylvatica 'Purpurea'), Wellingtonia/big trees, pin oaks (Quercus palustris), blue spruces (Picea pungens 'Glauca'), Bunya pine, flowering peach (Prunus persica cv.

[1] The golf course at least near the mansion is predominantly planted with Monterey pines (P.radiata), Lombardy poplars (Populus nigra 'Italica') and golden willows (Salix matsudana 'Aurea').

The square cast iron posts of the portico and verandas were made by Fletcher Brothers of Park Street, Sydney, and the verandah have ornate cast-iron lace to the balustrades and brackets.

An elaborately carved cedar staircase, very wide and generous was created by Richard Albon of Sydney with barley sugar balusters dominates the central hall.

[1] James Dalton, the prominent Orange merchant, purchased sections of the land from 187205 to establish a substantial family estate of 311 acres that he named Duntryleague after his birthplace in Ireland.

The estate included two gatehouses, an ornate entrance and gates, a stables, a dairy, 2–3 workers' cottages, a fern house, orchards, vegetable gardens for the household and extensive pastures for grazing.

In 1877 James was awarded the rare honour of being made a Papal Knight by Pope Gregory for his services to the Catholic Church and the large stained glass window in the hall of Duntryleague commemorates his investiture.

[19][1] Duntryleague property has strong historic associations with prominent merchant, pastoralist and townsman, James Dalton, and architect Benjamin Backhouse, its designer, R Scott & JJ McMurtrie, stonemasons.

Duntryleague has aesthetic significance with its prominent hilltop location, extensive grounds now a golf course, fine collection of magnificent mature trees, original estate elements including an axial entry driveway with gate keeper's lodge, notable house, terraced former gardens and tennis courts.
