[T]he shielding of industries which have been demonstrated by the war to be essential to the very life of the nation. I remember when I was appointed Minister of Munitions I found there were industries essential to national defence which had been very largely captured by our enemies. ... [T]hese essential key industries shall be preserved after the war, not because we anticipate another war, but because we are less likely to have another war if they know that we are quite ready for any challenge on a just ground.

Somewhat optimistically, as events in the last few years have shown, I declared that "the country is alive now as it has never been before to the essential value of agriculture to the community, and whatever befalls it will never again be neglected by a Government." It is still difficult to wean the urban population from a rooted habit of regarding the countryside as a picnicking ground, whose accessible amenities are restricted by fences and often destroyed by cultivation. They have not yet acquired a real comprehension of the essential importance of the land of the country to its security, its permanent prosperity and contentment.

The State must help to promote and encourage production. ... There must be none of that shrinking from national organization, national production, and national assistance. Germany never made that mistake. Take the most important of national industries, agriculture. Agriculture in the past has been overlooked in this country. It has been neglected, with the result that we have been dependent very largely on lands across the seas for our food. We have realized during the war the perils of this position. ... It is in the highest interests of the community that the land in this country should be cultivated to its fullest capacity, and I doubt whether there is a civilized country in the whole world where agriculture has received less attention at the hands of the State. ... The cultivation of the land is the basis of national strength and prosperity.

The welfare of the farmer is vital to that of the whole country.

Many new industries have arisen under the stimulus of dire necessity, and the encouragement of the Government. We have learned to make many things ourselves that we formerly imported from oversea. The war has taught us many lessons. It has taught us, among other things, to believe in ourselves and in the greatness of the resources and destiny of Australia.

Food is not only necessary for an individual’s survival, but also a nation’s

[T]his treaty [the Treaty of Rome<nowiki>]</nowiki>, which was precise and complete enough concerning industry, was not at all so on the subject of agriculture, and for our country this had to be settled. Indeed, it is obvious that agriculture is an essential element in our national activity as a whole. We cannot conceive of a Common Market in which French agriculture would not find outlets in keeping with its production. And we agree further that, of the Six, we are the country on which this necessity is imposed in the most imperative manner.

The agriculture sector has always been the main pillar for the sustenance of humanity in history. There used to be a time when our nation took the front position in this. It is commendable that we are beginning to witness an upsurge again. It is particularly gladdening that more and more women are embracing farming both as vocation and profession.

What is the next great lesson of the war? It is that if Britain has to be thoroughly equipped to meet any emergencies of either war or peace it must take a more constant and a more intelligent interest in the health and fitness of the people. ... I solemnly warn my fellow-countrymen that you cannot maintain an A1 Empire with a C3 population. (Cheers.) Unless this lesson is learned the war is in vain. Remember that the health of the people is the secret of national efficiency and national recuperation.

Lydick proved that permanent, well-arranged s and crop shelter belts are as much of an asset as barns or plows. They are as essential to agriculture as modern factories are to industry.

It ought readily to be conceded, that the cultivation of the earth as the primary and most certain source of national supply, as the immediate and chief source of subsistence to man, (...) has intrinsically a strong claim to pre-eminence over every other kind of industry. But, that it has a title to any thing like an exclusive predilection, in any country, ought to be admitted with great caution. That it is even more productive than every other branch of Industry requires more evidence, than has yet been given in support of the position. That its real interests, precious and important as without the help of exaggeration, they truly are, will be advanced, rather than injured by the due encouragement of manufactures, may, it is believed, be satisfactorily demonstrated. And it is also believed that the expediency of such encouragement in a general view may be shewn to be recommended by the most cogent and persuasive motives of national policy.

Anything is true, is essential to the national.

We all value too highly the immunity which this country has so long enjoyed from the horrors of an invaded land to endanger it for lack of timely prevision. That immunity at its very lowest has been for generations, and still is, a great national asset. It has undoubtedly given us the tranquillity and the security which has enabled us to build up our great national wealth. It is an essential part of that wealth. At the highest it means an inviolable guarantee for our national freedom and independence... We do not intend to put in jeopardy the naval supremacy which is so essential not only to our national existence, but, in our judgment, to the vital interests of Western civilisation.

This is the essence of the Agricultural Revolution: the ability to keep more people alive under worse conditions.
