Indeed, the work of an Engineer officer in India, as in England, is of

a very miscellaneous description, and I think it is no light subject

of pride to the whole corps that there is such a variety of talent

amongst our brother officers. In India, when I left the country,

besides Lord Napier, whose reputation belongs to the empire, we had

the ablest Lieutenant Governor in the late Sir H. Durand, who began

his career by blowing in the gates of Ghuznee. One of our officers

is Director of Indian Telegraphs another superintends the Great

Trigonometrical Survey, perhaps the greatest and most scientific survey

ever yet achieved; another is head of the Calcutta Mint; others were

amongst the ablest civil commissioners of the country; the astronomical

observations of another in connection with the last two eclipses have

been of the highest value to science; another has just received the

founder’s gold medal from the Royal Geographical Society for his works

on antiquarian geography; another has perished a martyr to science

amongst the deserts of Thibet; another has established a reputation as

the best accountant in India, and has since written the most famous

pamphlet of the age.

To complete my account of the Public Work agency, I must very briefly

refer to some of the financial aspects of the Department, which concern

the engineer. How is the money found for the various works of the

country? In this way:—

At the beginning of the financial year, the financial department of

the Government of India allots to each local government the several

sums that are authorized to be expended during the coming year, for the

several works that may have been sanctioned under the various heads of

irrigation, railways, roads, barracks, &c. These sums, thus provided

in the Public Works Budget, are allotted after due consideration of

the various budget estimates that have previously been submitted by

the chief engineers of the local governments, and they are not allowed

to be exceeded. For this, the superintending and executive engineers

are held responsible, and they must “cut their coat according to their

cloth,” _i.e._ arrange for the coming year’s work according to the

amount of money they are authorized to expend.

Every work is estimated for previous to sanction by the executive

engineer, and the estimate, after being checked by the superintending

engineer, is forwarded to his chief for sanction, who, if he approve

the design and estimate, recommends it for sanction by the local

government, or, in case of a large work, forwards it on to the supreme

government with his own remarks. If not satisfied with it, he may

return it for revision or explanation.

When a work is sanctioned and ordered to be commenced, the money being

also forthcoming for it in the budget, the executive engineer goes to

work. In the large presidency towns, and a few of the more important

stations, he may get the work executed by contract; but, as a general

rule, he will have to be content with procuring his materials by

contract, and perhaps getting his earthwork done in this manner. For

the rest, he will have to employ daily paid labourers, and occasionally

may have to import labourers from other districts, to organize them

into gangs, provide them with tools, and arrange for their food, water,

and temporary shelter. For this he has the assistance of his European

overseers, native sub-overseers, and _mistrees_ or head-artificers, and

as you will have to deal largely with these men, it may be as well if I

say a few words about them.

The European Overseers are nearly all non-commissioned officers or

privates who have volunteered from the various regiments in India for

the Public Works Department, and have been trained at the Roorkee

College. They are allowed to wear plain clothes, and are of course

struck off all military duty. As a rule, they are hard-working,

intelligent men, and many of them are most valuable subordinates, but

they are generally deficient in practical knowledge, are not very

conversant with the language, and are but too often given to drink.

The native Sub-Overseers have also been trained at Roorkee, and are

generally good draftsmen, surveyors, and estimators, but they are drawn

from the trading instead of the working classes, have no practical

experience, and lack physical stamina.

The Mistrees, or native head-masons and carpenters, are generally

intelligent and good men, quick to learn and easily managed, but few

have any theoretical knowledge.

The native labourer is patient, docile, and lazy, never drinks, and

is easily managed by anyone who understands him. Perhaps this is a

good place to say a word or two about the natives generally, and

their treatment by their English masters. Those who have any inherent

antipathy to black or brown skins had better not go to India, and

those who do go, and are anxious to find faults in the natives, will

have no difficulty in satisfying themselves on that score. But, as I

have already said, those Englishmen who live most amongst them, and

have most to do with them, get to like them most, with scarcely an

exception, and I can honestly say, after twenty years’ experience,

that I am no exception to the rule. Learn their language well, spend a

little time in studying their habits, prejudices, and modes of thought,

and I am sure you will find the trouble repaid. If they are not very

truthful, are indolent, and sometimes troublesome or even exasperating,

it is no light thing that they are singularly temperate, wonderfully

patient and good-tempered, very susceptible to kind treatment and good

management, and that strikes, drunken brawls, and grumbling discontent

are simply unknown.

* * * * *

Now, after so much preliminary dissertation, we may come to the more

professional part of our subject, and I shall begin by making some

remarks on the Materials with which the Indian engineer has to work,

after which we will proceed to discuss the particular constructions in

which they are employed, so far as these present any special points of

interest to those conversant with similar structures at home.

There are many varieties of _Stone_ in different parts of India, and

it is employed in the various forms of ashlar, rubble, &c., very

much as it is in Europe. Granites, limestones, and sandstones are

extensively used in the localities where they occur, but the cost of

carriage over bad roads to distant places necessarily restricts the

employment of this material. In Southern India, laterite, a clay-stone,

is extensively used, being easily worked, and becoming hard by exposure

to the air. In Upper India, Delhi and Agra are famous for their red

sandstone, and Jyepore for its white marble, of which the Taj and other

famous buildings are constructed. Bombay has also many varieties of

stone, notably the Poree-bunder limestone. Allahabad has some fine

quarries of sandstone, of which the new government buildings have been

constructed, and I recommend to your notice the account of the working

of the Purtarpore Quarries, in the Professional Papers on Indian

Engineering, as giving much practical information. Slate is generally

scarce and inferior, but some fine quarries have lately been opened out

at Dalhousie, and in the Khuttuk Hills, in the Punjab.

There is a kind of soft stone called moorum, found in Central and

Western India, which, though almost useless as a building material,

is extensively employed for road metalling. Kunkur, too, is quite

an Indian speciality, though it is almost entirely confined to the

North-Western Provinces. It is a peculiar kind of oolitic limestone,

found in beds just below the surface, and is of two kinds; one adapted

for building purposes, in which it strongly resembles artificial

concrete; the other answering admirably for road metalling, for which

purpose it is broken into lumps about the size of an egg, drenched

with water, and then rammed until perfectly smooth, after which it is

allowed to dry before the traffic comes on it.

The manufacture of artificial stone by Ransome’s process has been tried

at Bombay on a small scale, but not with success in an economical point

of view.

In the greater part of Upper India, and over much of the rest of India

as well, _Brick_ is the chief building material, and there are few

engineers in India who will not have much to do with brick-making.

I would therefore strongly recommend you to make yourselves well

acquainted with the latest improvements in the art, at the same time

bearing in mind certain Indian specialities, which will limit the

use of many of these methods; these are the cost of carriage, the

general absence of coal fuel, the dearness of other fuel, the absence

of skilled subordinates, and the disinclination of natives to be

driven out of their own customs, and to try experiments. But these

circumstances, remember, should only serve to guide your inquiries, on

no account to restrain them, for similar difficulties will always be

found in the path of improvement everywhere.

You will find very full information on Indian brick-making in the

‘Roorkee Treatise on Civil Engineering,’ and I shall only here advert

to a few salient points of the subject.

There is plenty of good brick-earth to be found, but the cost of

carriage prevents the same care being taken as at home in the selection

and admixture of clays. The clay is often tempered by hand, and then

taken straight to the moulding-table; but pug-mills are now pretty

common, worked by bullock power. The bricks are usually sand-moulded,

and are made of the English size, and stacked in temporary sheds to

dry. Brick-making machines have occasionally been tried; but their

expense, the difficulty of repair, and the cheapness of hand labour,

have always driven them out of the field. Hollow bricks, too, are never

seen; and as I think they would be found to be much cooler in the walls

of buildings than solid bricks, I would recommend anyone to acquire

information of their manufacture and cost.

Bricks are burned in clamps and kilns as in England; but it is only in

the neighbourhood of the very few coal localities in India that coal

fuel can be used; you will generally have to use wood, or in the case

of clamps, dried cow-dung and stable litter, commonly called _oopla_.

At Akra, near Calcutta, there is an extensive Government brickfield,

which I advise those of you who are able, to visit; Mr. Hickmott, the

superintendent, is a very civil and intelligent man. Hoffman’s kilns

have been lately tried, but not very successfully; and I advise you to

study the subject, economy of fuel being even more important in India

than in England. At the same time, the first cost of construction in

this, as in many other instances, must be clearly kept in view; for

this cost will have to be added to the cost of your bricks, and as it

would not pay to carry bricks far, and Indian distances are long, you

cannot afford an expensive construction, however good in itself, which

would all fall on the cost of perhaps two or three hundred thousand

bricks.

Coloured bricks are nowhere used in India, and their absence is much

to be regretted, for they would be most useful both for architectural

ornamentation and for floors and similar purposes. The proper clays,

on which, as you know, the colours depend, are found in some parts of

India; and careful search would doubtless bring to light others;—but

here again we are met by the fact that their manufacture requires skill

and capital, which are not found on the spot, and would have to be

imported. The same remark applies to terra-cotta and encaustic tiles,

which would be admirably adapted for Indian use, and would, moreover,

stand much heavier transit charges. But the Government cannot be

expected to enter the field as manufacturers, and so we must wait, I

suppose, for English capital and skill, or for the progress of native

enlightenment on these points.

Good ordinary bricks are, however, generally procurable in India, if

only proper care be exercised, and a fair price paid for them. The

bricklayers require close watching, and often systematic instruction in

the all-important subject of bond; for the common native brick is very

small, and laid in quantities of mortar with little care about bond; so

that native walls are really masses of concrete.

Brick arches are laid, as in England, either in half-brick rings, or,

in important works, with the bond carried right through the arch. The

natives are very skilful in constructing cheap centerings of dry bricks

and wooden soffits, plastered over with mud to the form of the arch,

which answer well when your centering is not liable to be carried away

by a rush of water. For large arches, whether built with regularly

framed timber centres or the common native centres, the French fashion

of striking them by means of hollow iron cylinders filled with dry

sand, supporting pistons on which the laggings rest, has been largely

employed of late, and is much to be commended. You will find it

described in Nos. 11 and 24 of the ‘Roorkee Professional Papers,’ as

also in the ‘Treatise.’

Masonry made of brick or stone laid in lime mortar is everywhere called

_pucka_ masonry. Bricks are, however, often laid in a mortar made

simply of thin clay with a little chopped straw in it, and the work

is then _kucha-pucka_ masonry. Sometimes sun-dried or unburnt bricks

are used, in the case of cheap buildings, for interior walls; or in

districts where the rainfall is scant, for exterior walls as well; this

is _kucha_ masonry. If well executed, and covered with a leping of clay

and cow-dung,—the foundations, tops of walls, and timber framings being

finished with pucka masonry—this cheap kind of work answers well in

very dry districts, and is cooler than burnt brick.

_Tiles_ are also extensively used in India for roofing purposes, and

they are often very badly made. I cannot, however, do more than draw

attention to the fact here. You will find plenty of information on

the subject in what was once described to me, the author, as “that

refreshing work,” the ‘Roorkee Treatise on Civil Engineering.’ The

tiles generally used in Government buildings are known as the Goodwyn

and Atkinson pattern tile. The hexagonal hollow tile introduced by

Colonel Fife for roofing purposes (and known as the Sindh tile), is

worth your attention; also the drainage tiles made by Captain Jeffreys

for the Ganges Canal. These I mention to illustrate what I have already

told you of the necessity of engineers becoming their own manufacturers

if they wish to make improvements.

We come now to the subject of _Limes_ and _Cements_, a very important

one in India. Lime is obtained in India from the limestone boulders

found in hill torrents, from kunkur, from beds of marl, or rather

calcareous tufa, and from limestone _in situ_. It is burnt with wood

fuel, sometimes in the open, generally in conical kilns, and is mixed

with sand, burnt clay, or brickdust, and sometimes other ingredients,

to form mortar in the usual way. The best lime is that procured from

boulders, which when mixed in the proportion of one part lime to two

parts of _soorkee_, or pounded brick, forms an excellent mortar for

hydraulic works. Kunkur lime, as a rule, is simply mixed with sand.

When lime is burnt with _oopla_, care must be used in sifting and

separating it from the ashes of the burnt fuel, otherwise, of course,

its strength will be greatly impaired. Artificial cements have scarcely

hitherto been made or used in India. You will find a valuable paper

on the relative cost of the manufacture and importation of Portland

cement, in No. 294 of the ‘Professional Papers’; also another paper by

Mr. Price, describing the manufacture of artificial hydraulic lime at

Kurrachee. There can be no doubt of the feasibility of the process;

but as a rule, the mortars employed, in Upper India, at least, are

excellent, if only proper care be used in their preparation. What is

chiefly required is a very quick-setting cement or mortar which, even

when used in building in water, shall harden in one or two days. This

is much wanted for repairs to canal works, where it is often absolutely

necessary to turn on the water before the mortar generally employed has

had time to set.

Concrete is not very much employed in India, though it has attracted

a good deal of attention lately; and some of the works on the new

Sirhind Canal were designed to be built almost entirely of it, such as

arches of 40 feet span. Indeed, with an abundance of excellent lime,

and a great scarcity of fuel, it seems curious that it has not been

more extensively used. Concrete blocks were recommended for the great

weir over the Ganges, by the Ganges Canal Committee, to be composed of

shingle, sand, and lime; and if proper apparatus be used for testing

the quality of the lime, there seems every reason to anticipate economy

and good work from such a mode of construction.

Lime is also used in stuccoes and plasters much as in England. Madras

is noted for this work, where the very beautiful _chunam_ plaster

for interiors of rooms, is as smooth, hard, and polished as marble.

Coarse sugar and pounded egg-shells are mixed with these more expensive

plasters.

Of _Timbers_ there is an immense number in India occasionally used; but

practically you will find yourself restricted to a very few varieties,

which are the only ones procurable in any quantity. In the Punjab, for

instance, the Deodar (Cedrus Deodara) is the principal wood employed,

being nearly identical with the famous cedar of Lebanon. It is found

in the Himalayan forests, where it is cut, thrown into the rivers, and

left there till the succeeding rains swell the stream and carry the

logs down below, when it is rafted and floated into the plains. It is

a very valuable timber, procurable in great scantlings, and used for

every purpose: trees of 7, 8, or 9 feet diameter at the foot, and 70

feet long, are by no means uncommon. In the North-Western Provinces

the Saul (Shorea robusta) is the principal tree; it has a long fibrous

grain, is straight and strong, of a reddish colour, and very valuable

for all purposes.

In Burmah and Western India, the Teak is the principal wood: its many

excellent qualities are doubtless well known to you. Other common

timbers are the Mangoe, used only for planking or furniture, and

readily attacked by insects; the Sissoo or Sheeshum, a hard, strong,

but crooked wood, in general request for many purposes, especially

furniture, as it takes a beautiful polish; the Keekur or Babool, an

acacia, a very hard tough wood, much used for carts; the famous Bombay

Black-wood, of which some beautiful specimens of carved furniture

are to be seen in the Indian Court of the International Exhibition;

the Toon, an inferior mahogany; the Sandal wood, which has a strong

perfume, and many others.

Timber in India is generally seasoned by the air or water process, and

is occasionally Kyanized or Burnettized. Well-seasoned timber stands

the climate well if carefully protected from white ants, those pests of

the East. For this purpose, the ends of beams fitting into walls are

generally charred and tarred, or the timber is soaked in a solution of

sulphate of copper; but the best preservative is carefully to prevent

any earth or mud from coming in contact with it. Wooden posts buried in

the earth will very soon be useless.

I don’t know that there is anything special to be said about the Indian

Carpenters, who are generally very fair, and sometimes very clever

workmen, though they _do_ squat on the ground, and hold a piece of wood

with their toes while they work the drill by means of a bow and string

with their hands. Carpenters’ benches were introduced in the railway

workshops at Lahore; but the superintendent told me that he had no

sooner turned his back than the men at once proceeded to squat on the

benches, so he gave them up in despair.

Of the _Metals_ used by the Indian engineer I need only mention Iron,

which is nearly all brought as pig from England. There are valuable

iron, copper, and other ores in India; but the great cost of fuel and

of carriage have hitherto prevented their being worked extensively.

A good deal of native iron is certainly brought into the market, and

worked up into tools, straps, bolts, &c.; but nearly all iron roofs

and bridges are imported from England; even those made at the Roorkee

workshops being manufactured from English iron.

Having now touched very briefly on the chief materials employed, I may

usefully give you some information with regard to _Wages_ of workmen

and _Cost_ of work. Wages, of course, vary more or less; but the pay of

a common labourer all over India may be fairly set down at 2 annas, or

3_d._ a day, and of an ordinary mechanic at 6_d._ to 7½_d._, with which

he finds himself in everything. A _beldar_, or navvy, will get 4½_d._,

and a skilled carpenter or mason from 9_d._ to 1_s._ These wages seem

very low compared with English prices; but you must remember that the

men all do far less work than an Englishman; thus, the lowest estimated

rate of common earthwork is now about 5_s._ per 1000 cubic feet, which

is at the rate of 50 cubic feet only per day for each man of the gang

employed.

Of course, I need not trouble you with a long string of rates; I only

wish to give you some idea of relative prices and money value. Good

ordinary brickwork will cost about 40_s._ per 100 cubic feet; ashlar

about 2_s._ per cubic foot; timber-work, 7_s._ per foot, “wrought and

put up.”

Taking into consideration the price of food, and other things, we may

fairly reckon, I think, the difference in the value of money employed

in constructing public works in India and in England as 1 to 4, _i.e._

that a work costing 10,000_l._ in India would cost 40,000_l._ in

England.

The Rupee, as you know, is nominally 2_s._, but really varies according

to the rate of exchange between 1_s._ 9_d._ and 1_s._ 11_d._ It is

divided into 16 _annas_—a copper coin worth about 1½_d._, which is

again divided into 12 _pies_, 4 of which make a _pice_. The 2-anna,

4-anna, and 8-anna bits correspond to our 3_d._, 6_d._, and 1_s._ There

is no standard gold coinage yet in India, though sovereigns will always

pass current, and 5 and 10 rupee coins have lately been issued. There

are now Government notes from 10 to 1000 rupees, which pass in all the

great towns, but will not be taken in smaller places without a discount.

As to Measures and Weights, in Upper and Western India we employ

the lineal, square, or cubic foot as the unit for our estimates and

calculations; in Madras, they use the cubic yard. Our lineal units are

generally understood, except, perhaps, the mile; natives generally

give distances in _kosses_, which vary from 1 to 2½ miles. The acre

is employed in Government papers, but is not known to the people,

who measure land by the _beegah_, which varies greatly in different

districts. The weights commonly used are the _maund_, _seer_, and

_chittack_, which are practically held to be 80 lbs. avoirdupois, 2

lbs., and 2 oz. respectively.

There is as great variety in India as in other countries in all local

weights and measures, and the people are as obstinate and suspicious

there as in England, and elsewhere, about any changes being made,—a

fact too often forgotten by the decimal and metrical doctrinaires in

their zeal to ensure a theoretically perfect system of standards.
