“Yea, though it should be mixed up amongst a thousand, they are all unlawful.” It is true that the rabbies endeavour to guard against such on accident, by forbidding the removal of such an egg on the holy day; but a Gentile or a child might, through inadvertently putting such an egg amongst others, produce great inconvenience or even loss, and to this the poor man must submit, or burden his conscience with a wilful transgression. But this law forbidding to eat or move whatsoever comes into existence on the holy day extends beyond the class of eatables. Wood accidentally broken on this day belongs to this class, and it is therefore unlawful to use it as fuel, or to move it. In like manner, ashes of wood that has been burnt on the holy day, is considered as having come into existence, and it is a sin to move it, when once it has cooled. And again, if a fire should go out on the holy day, it is a grave question whether the fuel that remains may be kindled again. Thus the conscience is burdened with definitions of unlawful, but the directions about things lawful are quite as numerous and perplexing. For instance, it is lawful to make a fire on a holy day, and to put on the pot for cooking, but an unlearned man or woman may commit a sin in the mode of doing it, and, therefore, the Baal Turim says, כשעושה האש ונותן עליה קדירה צריך ליזהר בסדור העצים ובנתינת הקדירה עליהם שלא יהיה דומה לבנין דאמר רב יהודה מדורתא מלמעלה למטה שרי , ממטה למעלה אסור ׃ “When one makes a fire and puts on a pot, it is necessary to be very careful in the arranging of the wood, and the mode of setting the pot upon it, so that there should be no resemblance to budding, for Rav Judah has said, every pile of wood begun from the top to the bottom is lawful, from the bottom to the top is unlawful.” (Orach Chaiim, 502.) For this reason very minute directions are given for the performance of each of these operations. The fire is to be made in the following manner:— העושה מדורה ביום טוב כשהוא עורך את העצים אינו מניח זה על זה עד שיסדר המערכה מפני שנראה כבונה . ואף על פי שהוא בנין עראי אסור אלא או שופך העצים בערבוב או עורך בשנוי . כיצד מניח עץ למעלה ומניח אחר תחתיו ואחר תחתיו עד שהוא מגיע לארץ ׃
